The sound driver is missing. Computer sound not working: how to fix the problem? The playback devices are empty

You lost sound on a Windows 7 computer and you still can't fix this problem? In this article, I will show you several reasons and methods to fix missing sound on your computer.

Often the reason for the lack of sound is simple user errors and it is very easy to solve them, but there are times when the sound disappears for an unknown reason. The main thing is not to get upset, as there is always a way out!

Possible reasons:

Checking the speaker volume

Maybe for many of you, this will seem commonplace, but I just want to ask you before checking other possible reasons for the lack of sound. Make sure the speakers are on and that the sound from the speakers is not at minimum. Also make sure that the speaker sounds indicator in the taskbar is not at minimum or worse off.

If everything is fine, press right click mouse on the "Speakers" icon and select "Playback Devices".

On the Playback tab, make sure your speakers have a green checkmark.

If nothing is displayed on the "Playback" tab, click right key mouse over an empty space and select the item "Show disconnected devices".

After that, our disabled speakers should appear, on which we right-click and the "Enable" item.

Lack of audio driver

Maybe you do not have a sound driver and the usual one is enough to fix the problem. If you are just now, then this is fine and all you have to do is find the audio driver for your computer and install them.

It is also possible that you have installed the wrong driver or it has been corrupted. In this case, you need to remove the installed audio driver and all sound devices, in the "Device Manager" ("Start" -> right-click on "My Computer" and select "properties", then click on "Device Manager").

After that, Windows 7 will try to automatically install the missing drivers.

If for some reason this did not happen, install the drivers manually.

Incorrectly connected speakers

Or maybe have you lost sound on your Windows 7 computer, due to incorrect speaker connections? It is quite possible! Make sure the speaker cable is plugged into the correct port, it is almost always green.

Conflict with installed programs

Rarely, but it happens that after installing any, the drivers fail. It is enough just to remove the conflicting program, and the problem is solved.

But what if we have installed a bunch of programs and do not know which of them conflicts with the driver? And it will help us with this, with the help earlier.

Sometimes, quite unpleasant things can happen to our computers. But it is important to know that any malfunction can always be corrected. And so, you turn on your PC, but during system boot you do not hear the familiar greeting melody. Perhaps someone will not even pay attention to such a trifle and continue to work as usual, turn on music or video, and suddenly, it turns out that there is no sound at all. Silence in the columns! Today we will consider possible reasons the problem and how to get the sound back by fixing the problem. All this can be done using the step-by-step instructions below.

But first, let's determine why the sound on the computer disappeared?

The cause of the malfunction can only lie in two places: in the hardware of your computer, or in its software. In other words, the absence of sound is a consequence of a malfunction in the Hardware PC, or is it related to setup operating system, incorrect work some programs. It should be understood that the occurrence of such a breakdown does not depend on the OS, its novelty. This happens in older versions such as Windows XP, as well as in the most recent Windows 8. It can also happen in Linux and other flavors of OS. Even if your equipment is the newest and most modern, the most expensive sound card, the highest quality speakers, you can still face a similar problem.

How do I restore sound on my computer?

From the beginning, we must find out the very cause of the problem. We will determine the reason for the absence of sound in various ways, starting with the simplest and most elementary ones.

To do this, we will follow, step by step, according to the following instructions:

Use the "Device Manager": "Start" - right-click on the line "Computer" - "Properties".

In the window that appears at the top left, click on the "Device Manager" line.

The first method is implemented very quickly, but practice shows that it does not always work, so if it does not help, use the second.

1. Disable the function "Use device in exclusive mode"

Right click on the speaker icon and select "Playback Devices"

The system disconnects the output devices themselves. This can be caused by system errors, device configuration changes, and user intervention. To correct this problem very easy! For this:

Resolved Issues

GRUB hangs and requires pressing Enter

The computer is overheating

Lack of required codecs.

The sound on the computer disappeared and if the above steps did not bear fruit, you can try reinstalling the sound adapter / card drivers. Most often, when the sound on the computer disappears, the drivers or the sound card itself are to blame. Through the device manager (start-control panel-hardware and sound-device manager) we find our sound adapter and look at its state (whether there is an arrow or an exclamation mark on the icon). If there is an arrow icon opposite the device, then you need to activate the device, press the other mouse button and press "activate". In the case of an exclamation mark, we will need to reinstall the driver. The driver can be installed from the disk that came with the computer, or you can download the required driver from the Internet for your model sound card.

A more drastic option is to roll back the system. System recovery is also carried out through the device manager (see the figure below).

The last resort in this series would be a complete reinstallation of the system. Immediately after reinstalling the system, fresh sound drivers are installed. After that we install all other programs. The sound may disappear after installing any program. This means there is a driver conflict.

Before doing something if there is no sound or poor sound quality, remember what you did, for example, yesterday, when the sound was still present on the computer. What additional software have you installed? The problem will most likely be solved if you uninstall this program. Or maybe you have deleted some desired file from a computer. If you did not install anything, then try the above 12 steps to fix the lack of sound. Surely something from the suggested will help you.

You can also use the Help and Support section of the Start menu.

Restoring sound

Restoring sound on a reinstalled system is done by installing a driver for your operating system. The driver can be downloaded from the official website of the sound card manufacturer.

Thanks to this manual, the majority of users will be able to solve problems with the absence or poor quality the sound being played. Sound problems, unfortunately, are quite common among users of outdated operating systems, as well as rare sound cards.

The most problematic task is to find drivers for your audio device. Since most sound cards are integrated into the motherboard, it can be difficult to determine the model of the sound card.

In most cases, Driver Pack Solution can help you select the correct driver for your sound card. This application includes many drivers for different operating systems.

Why did the sound disappear on Windows 7? It is possible that many Windows 7 users have had this problem at least once. This article contains the most common causes and solutions. Content:

So, what to do if your laptop doesn't sound working. The first step is to check for the necessary drivers for your sound card. They may need updating, or you may not have them at all. By the way, driver errors are half of the reasons why the soundtrack on a laptop disappears. In order to see which devices on your laptop or computer need driver updates, you need to open the device manager, which can be found in the control panel.

Perhaps the most commonplace, but at the same time the most common reason for the loss of sound is its unconscious shutdown in the mixer. A mixer is a system with which you can adjust the volume of specific applications. You can open the mixer by clicking on the corresponding label in the volume control window. After starting the mixer, make sure all parameters are nonzero.
No less common is another reason due to which the sound disappears on a laptop or stationary computer. Its essence lies in
In this window, one more parameter should be configured - the startup type. This parameter is responsible for starting the service at Windows startup. In order not to constantly start the service manually, I advise you to define this parameter as automatic.

In most cases, the front panel requires Realtek Manager to function. If you do not have it for some reason, be sure to reinstall it. Launching the manager from the control panel, go to the "Speakers" tab. Next, double-clicking on the folder icon in the upper left corner, check the box next to "Disable front panel slot detection"

If, after the performed operation of displaying information on the front, the panel is still not there, then most likely the BIOS installed in your laptop or computer is incorrectly configured. The BIOS system is present in any laptop, computer or tablet, and provides the operating system with API access to the hardware, including the front panel. To configure BIOS for front panel operation you need:

Exactly what type of hardware your front panel is, should be indicated on the motherboard or wires.

What to do if sound disappears on a computer running windows 7?

Why did the sound disappear on Windows 7? Perhaps many Windows users 7 this problem has occurred at least once. This article contains the most common causes and solutions. Content:

The main causes of loss of sound, as well as how to solve them
What causes the sound to disappear on a laptop, computer, etc.? In most cases, the reason for this is the user's own mistakes in handling the operating system.

So, what to do if the sound on your laptop is not working. The first step is to check for required drivers for a sound card. They may need updating, or you may not have them at all. By the way, driver errors are half of the reasons why the soundtrack on a laptop disappears. In order to see which devices on your laptop or computer need driver updates, you need to open the device manager, which can be found in the control panel.

In the manager window, all the drivers installed on a laptop, computer, etc. are systematized and presented. With it, you can check the availability, functionality or relevance of drivers. If any item is marked with a yellow triangle, you should pay attention to it! Devices responsible for audio playback are located in the "Sound, game and video devices" tab.

Perhaps the most commonplace, but at the same time the most common reason for the loss of sound is its unconscious shutdown in the mixer. A mixer is a system with which you can adjust the volume of specific applications. You can open the mixer by clicking on the corresponding label in the volume control window. After starting the mixer, make sure all parameters are nonzero.

No less common is another reason due to which the sound disappears on a laptop or stationary computer. Its essence lies in the system disconnects the output devices themselves... This can be caused by system errors, device configuration changes, and user intervention. It is very easy to fix this problem! For this:

Another common cause is the shutdown of the audio playback service. To start it again, go to Control Panel - Administrative Tools - Services. In the window that opens, find the "Windows Audio" service.

If the service is disabled, double-click on the service to open the change settings window, from where you can force the service to start by clicking the "Start" button.

In this window, one more parameter should be configured - the startup type. This parameter is responsible for starting the service when booting Windows... In order not to constantly start the service manually, I advise you to define this parameter as automatic.
Front panel audio cuts out
What to do if there is no sound on the front panel or there is no sound at all? The whole problem lies in the question "Why is there no sound?"

In most cases, the front panel requires Realtek Manager to function. If you do not have it for some reason, be sure to reinstall it. Launching the manager from the control panel, go to the "Speakers" tab. Next, double-clicking on the folder icon in the upper left corner, check the box next to "Disable front panel slot detection"

If, after the performed operation of displaying information on the front, the panel is still not there, then most likely the BIOS installed in your laptop or computer is incorrectly configured. The BIOS system is present in any laptop, computer or tablet, and provides the operating system with API access to the hardware, including the front panel. To configure BIOS for front panel operation you need:

When starting the system, namely during the demonstration of the manufacturer's logo motherboard installed on your laptop or computer, press and hold the "F2" key to exit to the BIOS menu.

Then you need to find and select the "Onboard Devices Configuration" item in the "Advanced" tab.

In the next window, you need to configure one parameter, namely "Front Panel Type", which is responsible for the type of front panel. There are usually 2 options: HD Audio and AC97.

Exactly what type of hardware your front panel is, should be indicated on the motherboard or wires.

If, even after setting up the BIOS, there is no sound on the front panel, then, perhaps, the sound card is covered and you will have to replace it, but in this case, the sound should disappear not only on the front panel. The sound may not work because the wire has come off.

Are you missing sound on your Windows 7 computer and can't fix the problem? In this article, I will show you several reasons and ways to fix missing sound on ...

Computers have long ceased to be used exclusively for any kind of computation. Many people watch videos, listen to audio recordings, and play various games on their PC. Sometimes, for various reasons, a problem such as “loss of sound” may appear. In this guide, we will look at the most common reasons why the sound disappears and suggest ways to solve the problem. So what to do?

Causes

Loss of sound is usually caused by many factors, which can be divided into two categories - hardware problems (headphones, speakers) or software problems. To begin with, consider the options for faults from the first group.

Reason # 1: Speakers, headphones and other audio devices

One of the most common options is speaker breakage or a problem with their connection. To fix it, you need to check:

Is the device securely connected to the outlet;
Is the volume set to zero?

Also, if possible, you can check if the speakers work on another or any device to which they can be connected.

Reason 2: Sound card does not work

Sometimes the cause of the loss of sound can be a banal malfunction of the sound card. But before replacing it, you will first need to eliminate all problems in the software part, which will be discussed below.

Reason 3: System settings

Before looking for reasons in deep settings, you should check if the sound is muted in the Windows taskbar. This will require:

Click on the speaker icon in the system tray next to the clock.
A small window will open where the volume is adjusted, and it is also possible to completely mute the sound. If the speaker is crossed out, then click on it and the sound will appear.
It is also possible that the crossed out circle is not displayed, but there is still no sound. In this case, check the volume control and set it to the up position.

Reason 4: Device driver

No sound may be due to a problem with the software, which is responsible for its stable operation. It may malfunction or be completely absent. To fix this problem, you will need to download drivers from the adapter manufacturer's website or, in the case of an integrated version,. After downloading, install them using the installer.

You can reinstall the driver in the following way:

Open the menu "Start" and go to.
In the new window, select.
Then press "Device Manager" .
You can also get to this section directly by entering the command into the window "Run" which opens by pressing the keyboard shortcut "Win + R" .
Next, open the item "Sound, video and game devices" .
A list will appear showing your sound card. Calling the context menu, you will need to select the item "Update drivers ..." .
Then you will have two options - automatic search or driver installation from a specific location. If you have not downloaded the sound card software, then you can use the first option, otherwise select the second one and specify the location of the downloaded files.
In addition, the map in the dispatcher can be marked with an arrow. This means that it is disabled and you need to return it to a working state. To do this, right-click on it and select the item "Engage" .

If an exclamation mark is displayed next to the device name, it means that the card is not functioning properly. You will need to do the following:

Windows will re-detect the card and configure it.

Reason # 5: Service

Also, the reason for the lack of sound may be a disabled service that is responsible for its functioning. To run it you need:

This section can also be accessed directly by entering the command services.msc out the window "Run" .

The service will start and the sound will appear.

Other causes and remedies

Another reason for the lack of sound can be a virus. In this case, vendors such as Doctor Web will help. If none of the proposed methods helped, and you are sure that the reason for the lack of sound is not in the hardware of the computer, then you can try to roll back the system using a restore point.

And finally, of course, you can resort to using the most radical options as well as replacing the card itself, but this should be done as a last resort if other options did not help you.

Description

After Windows installations no sound.
The sound disappeared suddenly.
Sound does not work on the Internet (browser) or games.
Sound does not work when connected to the front of the computer.

The problem is typical for various operating systems and computers (desktops, laptops, all-in-ones).

Cause

Problems can be software:

The driver is not installed.
Sound service is disabled.
Disconnect the playback device.
Incorrect system settings or system failure.
Disabled by a special button.
Incorrect update installation.
Virus.

Or hardware:

Failure of the sound card.
Defective speakers or headphones.
Broken cable.

Solution

The solutions to the problem presented below are arranged in order of frequency and ease of implementation. If one method didn't work, move on to the next.

As practice shows, it is not always possible to solve the problem with sound the first time - you can overlook something or not pay attention to an important detail. Go through all the points carefully, and if they did not help, go through them again.

1. Reboot

Before you do anything, just restart your computer - in some cases this will be enough.

2. Device and driver

Very often, the sound may not work due to an uninstalled, disabled or "crashed" driver. For example, you may encounter this problem after installing a new system or updating it. In this case, in the lower right corner of the screen, we will see a sound icon with a red cross or a prohibition sign:

In Windows 10, if we hover over the icon, we can see the error "Audio output device is not installed":

To solve the problem, go to the device manager. To do this, in Windows 10 (8), right-click on Start - Device Manager:

* in previous Windows versions right-click on "Computer" ("My Computer") - "Manage" - go to the "Device Manager" section.

Check that there are no yellow warning signs. The subsection "Sound, video and game controllers" should contain your audio playback device:

If you see that there is a device with an exclamation mark:

Also, you can see a device with a down arrow. This means the device is disabled. To enable, click on it with the right mouse button and click Turn on the device:

You can also try uninstalling the driver and installing it again.

3. Sound service

In the case of a disabled service, we will also see a sound icon with a red cross or a ban sign in the system tray (lower right corner):

But at the same time, everything will be in order in the device manager.

Right-click on "Start" - "Run" (or a combination of win + R) - enter the command services.msc- "OK"

* in Windows 7 (Vista, XP) you need to click on Start - Run.

In the window that opens, find the "Windows Audio" service. Its state should be "Working". If it is not, click on the service twice, set the startup type to "Automatic", click "Apply" and start the service:

If the service does not turn on or the power button is inactive, start the registry editor (command regedit) and follow the branch HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Audiosrv... Find the parameter Start and give it a value 2 :

After we restart the computer.

4. Muting the keyboard

If the keyboard has a mute key (most often on laptops or on gaming keyboards), try pressing it. It is usually located in the area of the F1 - F12 buttons. To press it, sometimes you need to use a combination with the Fn key.

Also, on some keyboards, this may be a separate button - look carefully and find a picture with a picture of a speaker.

5. Default audio device

If there are multiple audio devices in the system, such as an audio device and a video card with HDMI, then the latter can be set as the audio playback device. In this case, the audio stream will not go to the speakers or headphones, but to the monitor / TV connected to the computer.

Go to Control Panel(command control) - Sound... Make sure the correct default audio device is set:

To do this, click on the device with the right mouse button - Use as default.

6. Work of speakers and headphones

Check that the playback device itself is turned on. For speakers, this can be a dedicated button, for headphones, it can also be a dedicated button or the battery level in a wireless headset.

If the sound suddenly disappears, check the operation of the speakers or headphones, as well as the wiring. Check if the speaker or headphone plug is securely connected. Try connecting other speakers or headphones to your computer. Or you can try them out on another computer.

If the sound is lost after moving the computer or disconnecting the speakers, check that the connections are tight and correct. The playback device should be connected to the green connector, the microphone to the red one:

Try simply pulling the wires out of the connectors and reinserting them. Also try connecting to both the front audio jacks and the rear ones.

In the case of using monitor speakers, you must turn on the sound in the settings of the monitor itself.

7. Codecs and DirectX

In case of problems with software components, the problem may be observed on some sites, applications or games.

Install or update codecs such as K-Lite Codec Pack or VLC media player; reinstall DirectX.

8. Sleep mode

If the sound disappears after the computer wakes up from sleep mode, turn off the headphones or speakers - put it back into sleep mode - connect headphones or speakers - turn it on.

9. System error

Any problem with system settings or files may have an unexpected effect, such as loss of sound.

If the sound worked before, try checking system files for damage:

If the system finds corrupted files, restart your computer and check the sound.

10. Proprietary utility

Try playing with the sound utility settings. It is installed with the sound card driver and run from the control panel (command control) or system tray (icon in the lower right corner);

11. Troubleshooter

Use the remedy Windows errors... Click on the sound icon in the lower right corner - Troubleshoot sound problems... Follow the troubleshooting options offered by the system. Windows can automatically find and fix the problem.

12. BIOS setup

The integrated audio adapter can be disabled in the BIOS. In this case, we will not see our sound device in the device manager.

To check this setting, go to BIOS. We find the option to turn on the sound card - it can be called differently, for example:

HD Audio.
HD Audio Controller.
High Definition Audio.
Onboard HD Audio.
etc...

* you should be guided by words Audio and Sound... The section in which the desired option is most often located is called Advanced or Integrated peripherals.

Having found the desired section, we check that it is enabled - Enabled. If it is enabled, sometimes it helps to first turn off the sound card, then turn it on. After that, we boot the computer and check that a sound card appears in the devices.

13. Sound volume

The sound may disappear due to cranking the volume down to the minimum. Check that the speakers are not set to their minimum volume. Also, make sure that the volume in the audio settings is not too low:

On a laptop, the volume down button can be stuck - thus, it will always turn down the volume, preventing it from turning up. In this case, you can knock on the volume down button (among the F1 - F12 buttons, near F7).

Also due to wrong level volume may be sound in some applications, but not in some applications. Open the volume mixers - for this, right-click on the system icon in the lower right corner - select Open volume mixers:

In the window that opens, check that non-zero volume is set for all programs and devices:

* it so happens that the sound in the headphones works on the laptop, but the built-in speakers do not work. The problem, just, may lie in the set at 0 level for the speakers.

14. Turn on sound in a program or game

Some programs and games also allow you to control the volume and mute setting. In this case, you can accidentally turn it off - there will be no sound in this program, but in other applications they will work with sound.

With everyone's settings software product you need to understand individually.

Let's give an example for Google browser Chrome. In its settings, go to the section Additional - Site settings - Sound- check the position of the switch "Allow sites to play sounds (recommended)":

15. Scanning for viruses

In some cases, scanning your computer for viruses helps. To do this, you can use any anti-virus utility, for example, CureIt.

16. Active monitor

If the computer is additionally connected to the TV via HDMI, make sure that the normal monitor is active, and not the TV - otherwise, the sound may be transmitted to the TV, and not the speakers. You can switch the screen using the Win + P key combination.

17. Rollback updates

If the sound disappeared after Windows updates, you can simply roll it back. To do this, go to the control panel (command control) - in the "Programs" settings group, click on Removing a program:

In the menu on the left, click on View installed updates:

We sort the updates by date, so that the last ones are on top:

Delete Latest updates after which the sound stopped working. To do this, right-click on the update - Delete:

18. Front panel does not work

If the sound works when connected to the rear panel, but does not work when connected to the front panel, check the connection of the Audio cable to the motherboard.

To do this, you need to disassemble the computer and find the sound connectors on the motherboard:

And connect the Audio cable from the front panel to them:

* 1) modern cable; 2,3) can be found in older computers.

19. Startup

If the system reports "The device is in use by another application", try to disconnect one application from startup and restart the computer. If the sound appears, we turn on the programs, except for the one due to which the conflict arises.

20. Disconnecting wires from the computer

In some cases, this not quite obvious solution can help.

Disconnect all wires from the computer, including power. Press the power button once - the computer will not turn on, but the rest of the current will be reset. We reconnect all the cables to the computer, start it up and check the sound work.

21. Sound card

It is possible that the sound malfunction may be associated with a breakdown of the sound card. To test this, you can buy an inexpensive audio USB card(about 400 rubles) and connect it to your computer (do not forget to install the driver for it).

22. Reinstall Windows

If the above methods did not solve the problem, then reinstalling the system remains. This is not the most elegant method, but if all else fails, it remains. After reinstalling the operating system, do not forget to install the sound driver.

If this did not help, then with almost 100% probability we can say that the problem is hardware. Check your speakers, wires, connectors, sound card again.

What if ? With such a problem associated with the lack of sound on your computer, I think that every PC user had to meet. Welcome dear readers to my blog!

In today's article, I would like to pay special attention to the problem associated with the lack of sound on the computer, or more precisely, we will consider the most probable reasons due to which, in turn, sound disappears on our computer and, of course, we will learn how to independently eliminate the arisen Problems.

First of all, I would like to note that the problem of the lack of sound on the computer was, is and will remain a very extensive topic for discussion on the Internet. Therefore, it is no secret to anyone that the general principle of sound restoration in a computer boils down to the fact that you need to perform (check) a number of specific actions that will be aimed at sound restoration.

And it doesn't matter if you are even a novice user, because sometimes experienced users you have to spend a lot of time fixing a malfunction associated with the disappearance of sound in the computer. However, what if you have no experience at all to eliminate this type of malfunction? In the literal sense of the word, we can say that you just recently bought a computer for yourself and are starting to master it, and then BAM lost sound on the computer.

In this case, so that you can find out the cause yourself and eliminate it yourself, today's article will be not only useful for you, but also instructive because you will learn a lot of interesting information. Here we go?

No sound on the computer

So, when you turn on the computer, you find that there is no sound on the computer, and immediately wonder why there is no sound on the computer? At the initial stage of determining the cause of the lack of sound, it is important for you to know that the lack of sound on the computer can be caused by a malfunction either in the software or in the hardware.

Malfunctions in the software part can serve as a system failure, which in turn leads to damage to the system files responsible for playing sound. You can also add that the occurrence of a malfunction in the software part may be an incorrect setting of the sound scheme, the absence or damage of the audio device driver. Another reason may be faulty components (speakers, sound card). And in general, do not be too lazy to read the article:

Well, dear friends, I suggest you step by step consider the main reasons that may be the reason for the lack of sound in your computer. We will start, of course, with the simplest.

Step one... You should check the switch on the speakers, and if it is off, turn it on. Almost all speaker models are equipped with an LED that lights up when the speakers themselves are powered on.

Also check the position of the volume control.

Step two... Check if the speaker plug is connected to the computer correctly, the plug must be connected to the appropriate jack (the speaker jack is indicated in green).

Sometimes it is often necessary to notice that some users, after performing computer maintenance or, for example, after moving the computer to another room, inadvertently connect the speaker plug to a completely different socket in the computer, or even forget to plug in the plug altogether.

Therefore, there is no need to rush, do everything carefully and carefully, without rushing.

Step three... If the speaker plug is connected, it is correct and still , then you should check the speaker status on the taskbar. To do this, double-click on the speaker icon, as shown in the figure below, and make sure that the speaker status is active and the volume slider is not set to the minimum position.

Step four... At the next stage, you need to make sure if the speakers are working at all, because if the power indicator is on when the speakers are turned on, this does not tell us that the speakers are one hundred percent in good order. You can also connect headphones to your computer and check for sound. In general, do not be lazy and check the performance of the sound speakers on another computer or laptop.

Step five. Let's say that the speakers are completely functional, but there is still no sound on the computer. Then, in this case, you should open the task manager and check the status of the audio devices, or rather, make sure that the drivers on the audio devices are working properly, not damaged. In short, all devices must be recognized by the system, and the status of each device must not be indicated by an exclamation mark.

It is most likely that the drivers have been corrupted by viruses or actions malware, therefore, it is recommended to scan your computer for viruses before installing the driver.

If in your case there are such exclamation marks opposite the audio device, as shown in the picture above, then you should install the driver.

Read the article "" in order to properly check, scan your computer for malicious code in the system.

If no viruses were found, then you should proceed to installing the driver. You can find the drivers on the disc, which in most cases come with a sound or motherboard... You can also install the driver using the hardware ID code. You can find out in more detail how to install the driver by device code by reading my article:

and the status "device is working normally" is displayed, in the "General" tab

then you need to use the built-in diagnostic tool that is present in the operating room Windows system 7.

In some cases, problems with sound that have arisen can be completely eliminated thanks to the diagnostic tool. Open the control panel, then follow the link "System and Security" => "Support Center" => "Troubleshooting".

In the window that opens, click "Hardware and Sound"

and select "Play sound".

Then a window will open in which you will need to run the diagnostic tool by clicking on the "Next" button. If any malfunctions are revealed during the diagnostics, then at the end of the diagnostics a list of detecting and correcting the malfunction will be presented in the corresponding window.

Step seven... I have once lost sound on the computer for the simple reason that all playback devices were turned off. Therefore, be sure to check if the audio devices are enabled in the "Hardware and Sound" control panel. To do this, you need to right-click on the speaker icon, which is located in the lower right corner of the control panel, and select "Playback devices" in the menu that appears.

In the opened "Sound" window in the "Playback" tab, the status of the devices should be marked with a green check mark, as shown in the figure below

If none of the playback devices are displayed in the tab that opens, then right-click on the free part of the space and click "Show disabled devices" in the menu that appears.

At this moment, disabled devices should be displayed, which should be enabled by right-clicking on them and in context menu select "Enable".

As a result, the status of the playback device will be marked with a green check mark. You just have to save the performed procedure by clicking on the "Apply" and "OK" buttons.

Step eight... If, as a result of the above actions, there is still no sound on the computer, then the next step is to check the appropriate settings in the computer BIOS. Now I will not tell you how to enter the BIOS of my computer, as I already told in the article:

The only thing I would like to add is that you will need to check that the High Definition Audio parameter in the Advanced tab is enabled (depending on the BIOS version, the location of the parameter may differ, therefore, to more accurately determine the High Definition Audio parameter on your computer, use the reference literature of your mother board), that is, the value was set to "Enabled". Then restart your computer and check if there is sound in the system.

Step nine... One of my acquaintances once asked to fix the sound on his computer, according to him, the sound on the computer suddenly disappeared after installation special program to improve the sound quality that he downloaded from the Internet. After analyzing the situation and making sure that the absence of sound in the system was caused in the software part, I came to the conclusion that the sound was muted by the Windows service. And all because the program that my friend wanted to install was not completely installed in Windows and caused a crash or conflict.

So one of the reasons for the sudden disappearance of sound can be the actions of various malicious programs.

Therefore, if the sound disappeared after you installed a program, you should think about removing this program. I also recommend that you draw your attention to the fact that the "Windows Audio" service is enabled. You can check this in the following way. Click on the "Start" button and enter "Services" in the search bar, then left-click on the found value, as shown in the figure below.

Now in the "Services" window that opens, go to the "Windows Audio" service.

In the General tab, the startup type should be Automatic and the status should be Running.

If the service is disabled, then you should enable it, save the specified parameters and restart the computer.

Step ten... At this step, you should install another known working sound card, since it is quite possible that your sound card is out of order. By the way, before installing a sound card, perform preventive maintenance on your computer, an operation that is very, useful and necessary for a stable and correct work computer. Anything is possible that the sound will appear after maintenance work. In the article "" you will learn the nuances that should be taken into account when cleaning your computer.

Step eleven... So, if you still have, and you have done all the above actions by me, then you can try to return the system to its previous state using the previously created control points... If you do not understand what I am talking about, then read these two articles:

After all, it is possible that you lost sound on your computer because of a system file you accidentally deleted, which is responsible for the sound of the file. Therefore, the rollback of the system to a previous state in some cases helps to eliminate the malfunctions that have arisen when working at the computer.

Concluding today's article, I hope that the information presented in this lesson was in demand for you and you got useful recommendations for yourself. I remind you that if you want to keep abreast of new articles, then fill out.

And finally, I would like to know from you, what other malfunctions associated with the lack of sound did you have to fix?

See you all in the next article =>

The computer has long ceased to be an exclusively apparatus for work and calculations. Many users use it for entertainment purposes: watching movies, listening to music, playing games. In addition, using a PC, you can communicate with other users and learn. Yes, and some users work better with musical accompaniment. But when using a computer, you may encounter such a problem as the lack of sound. Let's see how it can be caused and how to solve it on a laptop or desktop PC with Windows 7.

The loss of sound on a PC can be caused by various circumstances, but all of them can be divided into 4 groups:

Acoustic system (speakers, headphones, etc.);
PC hardware;
Operating system;
Applications that play sound.

The last group of factors will not be considered in this article, since this is a problem of a specific program, and not the system as a whole. We will focus on solving complex problems with sound.

In addition, it should be noted that the sound may be lost, as due to various breakdowns and failures, and due to incorrect configuration of serviceable components.

Method 1: speaker malfunctions

One of the common reasons why the computer does not play sound is problems with the connected acoustics (headphones, speakers, etc.).

First of all, carry out the following verification:
- the speaker system is connected to the computer correctly;
- whether the plug is included in the power supply network (if such a possibility is provided);
- whether the sound device itself is turned on;
- whether the volume control on the acoustics is set to the "0" position.
If possible, check the performance of the speaker system on another device. If you are using a laptop with headphones or speakers connected, check how the sound is reproduced by the built-in speakers of this computer device.
If the result is negative and the speaker system does not work, then you need to contact a qualified technician or simply replace it with a new one. If on other devices it reproduces sound normally, then it is not about acoustics and we move on to the following solutions to the problem.

Method 2: the system tray icon

Before looking for faults in the system, it makes sense to check if the sound on the computer is turned off with standard instruments.

But a situation is possible when the crossed out circle is absent, but there is still no sound.

There is also an option when the icon in the form of a crossed-out circle is present at the same time and the volume control is lowered to the limit. In this case, you need to alternately carry out both of the above manipulations.

Method 3: drivers

Sometimes the loss of sound on your PC can be caused by a problem with the drivers. They may be incorrectly installed or missing altogether. Of course, it's best to reinstall the driver from the disc that came with the sound card installed on your computer. To do this, you need to insert the disc into the drive and, after starting it, follow the recommendations that will appear on the screen. But if for some reason you do not have a disk, then we adhere to the following recommendations.

Click "Start"... Next, move to "Control Panel".

Move on "System and safety".

Further in the section "System" go to subsection "Device Manager".

You can also navigate to the Device Manager by entering a command in the tool field "Run"... We call the window "Run" (Win + R). We enter the command:

Push "OK".

The Device Manager window is launched. Click on the category name "Sound, video and game devices".

A list will drop out where the name of the sound card that is installed in your PC is located. Click on it with the right mouse button and select from the list "Update drivers ...".

A window is launched, which offers to make a choice of how to update the driver: perform an automatic search on the Internet or specify the path to a previously downloaded driver located on the hard disk of the PC. Choosing an option "Automatically search for updated drivers".

The process begins automatic search drivers on the Internet.

If updates are found, they can be installed immediately.

If the computer fails to detect updates automatically, you can search for drivers manually via the Internet.

To do this, just open your browser and type in the name of the sound card installed on your computer into the search engine. Then, from the search results, go to the website of the sound card manufacturer and download the necessary updates to your PC.

If there is an exclamation mark next to the name of the audio equipment in Device Manager, this means that it is not working properly.

Method 4: enable the service

There may be no sound on the computer either because the service responsible for its playback is disabled. Let's find out how to enable it on Windows 7.
1. In order to check the health of the service and, if necessary, enable it, you should go to the Service Manager. To do this, click "Start"... Next press "Control Panel".
2. In the window that opens, click "System and safety".
3. Then go to item "Administration".
4. The list of tools is revealed. Stop your choice on the name "Services".
  
  You can also open the Service Manager in another way. Dial Win + R... A window will open "Run"... Enter:
  
  Push "OK".
5. In the drop-down list, find the component named "Windows Audio"... If in the field "Startup type" worth the value "Disabled", but not "Works", then this means that the reason for the lack of sound lies precisely in the stopping of the service.
6. Double-click the left mouse button on the name of the component to go to its properties.
7. In the window that opens in the section "General" make sure that in the field "Startup type" there was definitely an option "Automatically"... If a different value is set there, then click on the field and select the required option from the drop-down list. If you do not do this, then after restarting the computer, you will notice that the sound disappears again and the service will again have to be started manually. Then press the button "OK".
8. After returning to Service Manager, re-highlight "Windows Audio" and in the left part of the window, click on "Run".
9. The service starting process is in progress.
10. After that, the service will start working, as indicated by the attribute "Works" in field "State"... Also note that in the field "Startup type" was set to "Automatically".
After completing these steps, the sound on the computer should appear.

Method 5: check for viruses

One of the reasons why no sound is played on the computer may be a virus infection.

As practice shows, if the virus has already made its way onto the computer, then scanning the system with a regular antivirus is ineffective. In this case, a special anti-virus utility with scanning and disinfection functions can help, for example, Dr.Web CureIt. Moreover, it is better to scan from another device, having previously connected it to a PC in relation to which there are suspicions of infection. As a last resort, if it is not possible to scan from another device, use removable media to complete the procedure.

During the scanning procedure, follow the recommendations given by the anti-virus utility.

Even if it is possible to successfully eliminate the malicious code, the sound recovery is not guaranteed yet, as the virus could damage the drivers or important system files. In this case, it is necessary to perform the procedure for reinstalling the drivers, as well as, if necessary, perform a system recovery.

Method 6: restore and reinstall the OS

If none of the described methods gave a positive result and you made sure that the cause of the problem is not acoustics, it makes sense to restore the system from a backup or roll back to the previously created restore point. It is important that the backup and restore point are created before the sound problems start, and not after.

If you do not have a system restore point on your computer that was created before the sound failure occurred, and there is no removable media with backup copy, then in this case you will have to reinstall the OS.

Method 7: faulty sound card

If you exactly followed all the recommendations described above, but even after reinstalling the operating system, the sound did not appear, then in this case, with a high degree of probability, we can say that the problem lies in a malfunction of one of the hardware components of the computer. Most likely, the lack of sound is caused by a breakdown of the sound card.

In this case, you must either seek help from a specialist, or independently replace the faulty sound card. Before replacing, you can pre-test the performance of the sound element of the computer by connecting it to another PC.

As you can see, there are many reasons why a computer under Windows management 7 sound may be lost. Before proceeding to fix the problem, it is best to find out the immediate cause. If this cannot be done immediately, then try to apply various options for correcting the situation, according to the algorithm given in this article, and then check if there is a sound. The most radical options (reinstalling the OS and replacing the sound card) should be done last, if other methods did not help.
