One of the reasons for the lack of sound on the computer may be: failure of the speakers (headphones), incorrect settings audio parameters, sound card malfunction or motherboard, various software failures that could result from viruses or after installing incompatible applications and drivers. So what to do if the sound disappears? First you need to determine the cause and then eliminate it. In general, the task is quite simple. Below we offer instructions for solving the problem in operating rooms. Windows systems 7, Windows Vista and Windows XP.1. Check your volume controls
In the lower right corner of the screen, where your clock is located, there is an icon that looks like a speaker.
If you do not have this icon (this may happen in Windows XP), then you should check the settings through the control panel in the “Sounds and Audio Devices” section (see point 4, for Windows XP).
By clicking on this icon with the left mouse button, make sure that the sound is not turned off and the volume control is not lowered all the way down.
Now click right click mouse on the same speaker icon and open “Volume Mixer”. In the window that opens, check whether the controls are enabled.
">(Volume mixer window in Windows XP)
If you are in these settings you cannot do anything due to the fact that all parameters are deactivated (highlighted gray), then you need to check the audio device for functionality in the task manager (step 3) and if problems are also identified there, then you will need to reinstall the audio driver (step 6)
2. Check the physical connections of audio output devices
Before you start checking your sound card settings and status, make sure your speakers (or headphones) are turned on and connected correctly. The output on the audio card for connecting sound speakers is marked green.
If your computer has more than one sound card, then make sure that the speakers are connected to the connector of the working card (used by the system). Make sure that the wire leading from the speakers to the system unit has not come loose.
If possible, check the functionality of the speakers on another computer. Or connect another audio device to the audio output.
3. Check the functionality of the sound card in Device Manager
To get to the Device Manager window...
IN Windows7 or Vista click:
Start -> Settings -> Control Panel -> Device Manager.
IN Windows XP:
Right-click on the “My Computer” icon, select “Properties”, go to the “Hardware” tab and click “Device Manager”.
Your audio device should be listed under Sound, Video and Game Devices.
If the device is missing, undefined, or has an exclamation mark next to it, then the corresponding driver is damaged or missing. In this case, the driver needs to be updated or completely reinstalled (see point 6).
4. Check your audio settings
To get to the audio settings window in Windows7, Vista click:
Start -> Settings -> Control Panel -> Sound.
A dialog box will appear in front of you with a list of your devices. In our case, there is one device that is set by default:
The correct operation of the audio will be indicated by a corresponding inscription under its name and a green check mark next to the device icon.
If you see a different picture in this window, with obvious problems with the device’s operation, then you need to try reinstalling its driver (see point 6)
On Windows XP:
Click Start -> Settings -> Control Panel -> Sounds and Audio Devices
On the audio tab, in the audio playback section, make sure your device is correctly identified and set to default:
Go to the Volume tab. Make sure that there is no checkmark next to the “Mute sound” item. It is also necessary that the mixer volume be set above zero.
If all the settings in this section are correct, then proceed to the next step.
If the mixer volume control cannot be moved, and at the top instead of the name of your audio device you see the message “No audio devices”, then most likely your audio driver has crashed or is faulty. sound card(see point 6).
5. Check if the required “Windows Audio” service is running
Go to Start -> Settings -> Control Panel -> Administrative Tools -> Services.
In the window that opens, find the “Windows Audio” service.
If this service is running and running in Auto mode, as shown in the figure, then close the window and proceed to the next step.
Otherwise, if the service is disabled, you need to enable it. To do this, select it with the right mouse button, and in the drop-down menu select “Properties”.
In the properties window, do the following:
1) Set the startup type to " Auto»;
2) Click the button Launch" (Windows7, Vista) or " Start"(Windows XP);
3) Click " Apply" And " OK»;
If it doesn't help, move on to the next step.
6. Reinstall your audio device driver
When you find problems in Device Manager or the audio settings window that clearly indicate that the sound device is not working properly, the sound device driver is most likely damaged or not working correctly, which in this case needs to be updated or completely reinstalled.
To do this you will need a sound card driver. It can be found on the disk that comes with the card itself, or on the driver disk for the motherboard when the sound device is integrated into the motherboard. The motherboard disk is included with the computer upon purchase. Pay attention to whether the drivers are designed for the device you are using. operating system. If you have Window 7 installed and the drivers are on disk for Windows XP, then you need to go to the website of the manufacturer of your card (or motherboard) and download the required driver.
Go to “Device Manager” (“Control Panel” – “System” – “Hardware” tab – “Device Manager”) and uninstall the currently installed audio driver. If this is not the case in your case, then look for the name “Multimedia Audio Controller”. At the same time, remove all installed audio-video codecs from your computer. This can be done in the Add or Remove Programs snap-in from the Control Panel. Then reboot your system.
If you are running Windows 7, then after rebooting the system should update missing drivers automatically using technology Plug and Play.
For manual installation, insert the driver disc into the drive.
Open the Device Manager window. Look for the section with the word "audio" or "multimedia." Double-click the device to open its properties. Select the Driver tab and click the Update button. In the menu that opens, the system will ask how to install: automatically or manually. Select the second one and click the “Next” button:
In the window that opens, check the box next to “Include the following search location” and use the “Browse” button to specify optical drive with disk. Click the “Next” button to begin searching for the driver and then installing it.
Upon completion, the system will notify you that the driver is installed and the equipment is ready for use. The sound may appear now or after a reboot.
7. Check your BIOS settings
No sound in Windows may also be due to the fact that the integrated audio card is turned off in BIOS settings. To check this, at the very beginning of turning on the computer (before the system boots), press the Del button. On some computers this may be the F2, F10, or F12 key. Find the sound card in the list of motherboard devices and make sure that the switch opposite is set to the “Enabled” position.
! Of course, another reason could be a broken sound card. But before you buy a new one, make sure that you have tried everything listed above and nothing has given you the desired result.

That's it: Girls, please help. After I cleaned out unnecessary programs and documents, the sound disappeared... When I try to play a file, the Do not play audio window appears. No audio device was detected on the system. The movie will play, but you won’t hear the sound. When you enter Start-Programs-Standard-Entertainment-Volume, it says No active mixer devices found. What does this all mean How to get the sound back There was no sound in the dark, I downloaded all the applications that are listed there, it doesn’t help
Whopeave 2009-12-26 05:59:33
Rearrange the sound card driver. What sound card do you have? Are there unidentified devices in the device manager (start---settings---control panel---system---hardware tab---device manager)? If there are no unknown incomprehensible devices, we find our sound box in the sound, video and gaming devices (probably the name will contain the word sound, or something like speakers with numbers, or better yet, attach a screenshot of the dispatcher window), poke the sound box with the right Click the mouse and select update the driver. Alternatively, you can simply delete the device (Del button), or all devices similar to the audio device in the manager, having previously armed yourself with drivers for them (usually on the included disk, or on the PC’s hard drive, as an option - first download from the manufacturer’s website). After deletion - either reboot, or in the manager the action is to update the config. equipment. Briefly something like this. In general terms... If you want to be specific (for example, where to download drivers from and which ones) - write what kind of hardware you have.

SeregA S.U. after clicking update the driver, the Hardware is not installed because the wizard could not find the required software appears. And in the Device Manager near the Audio Device on Hight Defention Audio Bus there is an exclamation mark in the circle. What is hardware? Maybe this Intel Core 2DuoCPUE4500 @ 2.20 GHz2.20 GHz, 2.00 GB RAMWindows XP 2002
Ongthe 2010-01-06 12:18:49
Fluffy, so when you update the driver, do you indicate where to update from? You prepared the driver yourself (in the sense that you found it, it is on your hard drive or on a CD in a place known to you, which you will tell the hardware installation wizard about). During the driver update process, tell the wizard that the search will be in the specified location, indicate with your hands the place where you have the driver. Have you tried just removing this device and rebooting? Naturally, you will also need a driver. What is hardware? Maybe it's just General characteristics, are not of particular interest. Here, the manufacturer and model of the motherboard will be more interesting (as I understand it, the sound is built-in).

In such a case, I simply rolled back the system to the state before cleaning. I don’t remember how I did it, because... I did it at random. But it wasn’t difficult. Of course, the cleaning results will be lost, but the sound will most likely appear. And the cleaning can be repeated, taking into account the experiment carried out. Smiley - does not apply to you, but to me. I did all this. And repeatedly, but I gained invaluable experience
Yould 2010-01-16 08:49:47
If you really want to roll back the OS, go to start --- programs --- standard --- utility --- system restore. Just a few points: 1. the recovery system, in principle, had to be turned on before and recovery points saved (AXIS itself does them during events that are important from its point of view, but it can also be done manually at any time)2. restoration may bring back everything that you carefully cleaned 3. restoration may not help. In general, advice to you: if you don’t know, it’s better not to clean anything, especially in automatic modes. And if you’re planning to clean it, take a snapshot of the system, or at least create that same restore point (although it doesn’t always help, but at least that’s it). It would be nice if your system cleaner could (and would) make copies of the registry with which it works.

Fluffy, do you have disks with native motherboard drivers? They usually come with system unit at the time of buying. If the sound is built-in, then it will be on the motherboard disk required driver. And by the way, so that the system itself conducts the search, you can delete the device that is listed in the device manager with exclamation point, after restarting the computer, the system itself will try to search for the required driver.

Girls, thank you so much to everyone for your answers Fluffy, do you have disks with native motherboard drivers? They are usually supplied with the system unit upon purchase. If the sound is built-in, then the necessary driver will be on the motherboard disk. And by the way, in order for the system to conduct the search itself, you can delete the device that appears in the device manager with an exclamation mark; after restarting the computer, the system itself will try to search for the required driver. Xena, yes. When you start this disc, the system is automatically checked and it says that the drivers are installed. In my diagnostics window, To check the volume setting, Open the Volume window. Check that the Off checkbox is turned on. everything is removed, and set the required volume and balance levels......the Volume window does not open It says active devices - no mixers found...And also about the drivers..in Audio drivers it says the driver is turned on, but was not started What is it you can run
Thanks westw The problem was solved by installing WindowsXP-KB958644-x86-RUS and disabling the Server and Workstation services. In details system error applications svchost.exe - Generic Host Process for Win32 Services (solution dated 09/24/2006 with additions dated 12/08/2008)
This problem is associated with several bugs in the "Server" system service (in particular, in the netapi32.dll module) when working on a network under Windows XP SP1/SP2/SP3. To fix this problem, users of single machines (that is, whose computers are not connected to other machines by a local network) need to do the following: press the Microsoft + R key combination (explanation: “Microsoft” is a key with the image of the Microsoft corporate icon); in the window that appears with command line type the text msconfig and click "OK"; in the window that opens, go to the “Services” tab and uncheck the “Server” and “Workstation” items, then also click “OK”; Restart your computer and in the message window that appears, check the box and click “OK.” The changes made will not affect the performance of the Internet connection or anything else. Attention! Important! If your computer is connected to other computers local network and contains shared folders and files that other participants should have access to working group, or your computer is a server-router (acts as a gateway) through which other computers connect to the Internet, or you have a VPN connection that uses a gateway on the local transit server of your Internet provider, then the “Server” and "Workstation" cannot be disabled, because this will lead to inoperability of local connections with other computers. In this situation, to fix the above problem, you need to download from the Microsoft website and install patches with the following numbers on your computer: for Windows XP SP1 - KB921883 and KB923414; for Windows XP SP2 - KB923414, KB924270 and KB958644; for Windows XP SP3 - KB958644. For Russian speaking Windows versions(if you used the Russian language system interface, then the link below will not work for you; see below link for English. interface) patches can be downloaded from here: [Only registered users can see links] For the English version of Windows (with the original English interface or with the Russian one installed using a Russifier) use the link [Only registered users can see links] Before installing patches, be sure to unload from the system (only from memory - no need to delete anything!) antiviruses and firewalls, such as, for example, Outpost Pro, ZoneAlarm Pro, Kaspersky Internet Security, etc. Please note that installing patches while security software is active may lead to incorrect operation of the system; You can reactivate the protection immediately after installing the patches on the system. Also, do not forget to restart your computer after installing each patch.
