Moreover, often the breakdown is minor, and it can be fixed on your own without the involvement of third-party highly qualified specialists. The second option is the help of a service center. It's more difficult decision, and you should use it only when you can’t do it on your own.

To solve the problem of how to turn on sound on a computer, you must start by checking the connections. The headphone or speaker jack must be strictly connected to the green pin sound card. If you use either speakers or a subwoofer to output sound, you need to check that there is power. This should be indicated by the LED on the front panel. If the LED is off, the network connection is being checked. AC voltage. It is also necessary to check the toggle switch for turning on the speaker system. Sometimes it is located on the front side, on other systems it is hidden on the back side. If there are no problems with switching and supplying voltage, then the next step is to check. It is recommended to set it to some middle position. This will eliminate the possibility that the volume is set to minimum and will greatly simplify the procedure of how to turn on the sound on your computer.

At the next stage, you need to check that the drivers on the sound card are installed correctly and correctly. To do this, go to the “My Computer” shortcut and select “Properties”. Then select “Device Manager”. Then in the “Sound Devices” section we check that the drivers are installed correctly. If everything is correct, then there are no icons nearby. If there are icons (exclamation mark, for example), you need to reinstall the drivers. This is one way to solve the problem of how to turn on sound on a computer.

Next you need to launch the drivers. This can be done on the taskbar double click left mouse button on the corresponding icon. The second option is through the “Start” button, “Control Panel” and selecting the appropriate icon in it. After starting, you need to go to the test window and check by alternately clicking the left mouse button that the left and right speakers are triggered. With this test, it allows you to check the signal output for sound system and its operation.

If the performed manipulations did not bring positive result, it makes sense to contact service center. The problem is much deeper, and it is almost impossible to solve it on your own. If you contact a specialist, he will definitely find the reason why the acoustics are not working and will bring your computer system back to life.

Video - How to turn on speakers on Windows 7

Instructions for troubleshooting sound problems on your computer.

Why might there be no sound on my computer? How to correct this annoying misunderstanding? Sometimes the user can adjust the sound on the computer from the keyboard, but if the sound disappears, then there is no point in pressing the keys. First you need to find out the cause of the problem and then fix it. Here are common reasons why sound may disappear on your computer.

Malfunction of speakers or headphones
Audio settings are not configured correctly
The sound card or motherboard is faulty
Software crashes due to viruses
Installed incompatible applications or drivers

Below are instructions, consisting of 7 points, for troubleshooting for operating rooms Windows systems Vista, 7 and XP.

Step 1: Check the volume controls

Find the speaker icon in the lower right corner of your monitor. If the icon is not displayed (as in Windows XP), go to settings - control panel - section “Sounds and audio devices” (more details in point 4 about Windows XP). By clicking on the icon, make sure that the volume slider is not all the way down, and also that the sound is not muted. Sometimes there is a volume button on the keyboard.

Call up the context menu with the right mouse button and open “Volume Mixer”. In the dialog box, check that all controls are enabled. If the controls are active, you need to turn them on.

If nothing can be done in these settings and the sound does not appear, everything is selected gray(the parameters are deactivated), then move on to the next point: checking the audio device for functionality in the task manager (step 3). If there are problems there, you need to reinstall the audio driver (step 6).

Step 2: Physically connect the audio output

Before checking the settings and condition of the sound card, make sure that the speakers (or headphones) are connected correctly and that they (the speakers) are turned on. On an audio card, the speaker connector is usually marked green.

If your computer has more than one sound card, make sure that the speakers are connected to the connector exactly work card(which is used by the system). Check to see if the wire connecting the speakers and the system unit has come loose.

If possible, test the speakers on another computer or connect another sound device with audio output and check the sound.

You can also check to see if you accidentally pressed the mute/unmute button on your keyboard. Some computer keyboards have this button.

Step 3. Checking the sound card is working

To enter the “Device Manager” dialog box, click:

In Windows7 and Windows Vista

Start -> Settings -> Control Panel -> Device Manager.

On WindowsXP

Go to the context menu “My Computer”, “Properties”. Next, find the “Hardware” tab and click “Device Manager”.

Your computer's audio device is displayed in the Sound, Video and Game Devices icon.

If the device driver is damaged or missing, the device icon will not be displayed, is not defined, or is next to Exclamation point. In this case, the driver must be updated or restored completely (step 6).

Step 4: Check your audio settings

You can check the audio settings on your computer using the Audio Settings window. In Windows 7 or Vista, to open the audio settings window, you need to select the Sound icon in the Control Panel, in the Settings section of the START menu. By the way, the Start button can also be on the keyboard, and with its help you can immediately enter the menu without using the mouse.

In the dialog box you will see a list of devices on your computer. In our example, this is only one device, set by default:

If the device is working correctly, next to the icon is located green tick and the inscription “working”.

If something else is visible, and there are some problems with the device, you need to reinstall the driver (step 6).

For Windows XP:

You need to enable “Sounds and audio devices” in the Control Panel. (Setting in the START menu)

Make sure the device is recognized correctly on your computer and is installed by default. To do this, go to the Audio tab, in the audio playback section.

Go to the "Volume" tab. Uncheck the “Mute sound” checkbox if it is there. You also need to make sure that the mixer volume is set above zero.

If all the settings in this section are correct, you can move on to the next step.

If your sound driver has crashed or your sound card is faulty, then the mixer volume control cannot be moved, and in place of the name of the audio device you will see a message about the absence of sound devices (step 6).

Step 5: Check the Windows Audio service

Go to Services – Administration – Control Panel – Settings - Start

(or through the command line: on the keyboard Start, then “Run”, in command line Type the command services.msc on your keyboard. Click OK.

In the window that appears, find the “Windows Audio” section.

If the service is running in automatic mode, you can move on to the next point.

Otherwise, if the service is disabled, you need to enable it. IN context menu services, select "properties".

In the Properties dialog box, do the following:

Enable startup type "Auto"
For Windows7, Vista, click the “Run” button; for Windows XP, the “Start” button
Click “Apply” and “OK”;

If it doesn't help, move on to the next step.

Step 6: Reinstall the audio device driver.

If there are problems in the audio settings window or in the device manager, there are signs that indicate that the sound device on the computer is not working correctly, then this most likely means that the sound driver is not working correctly or that it is damaged. In this case, the driver must be reinstalled or updated.

This can be done using the sound card driver file. It can be on a disk, included with the card, or along with drivers for the motherboard if the sound card is integrated into system board. A disk containing motherboard drivers is included with the purchase of your computer. You need to pay attention to whether the drivers are suitable for your operating system. If the drivers are for Windows XP and you have Windows 7, you need to download necessary files from the motherboard manufacturer's website. Unlike Windows 7, on Windows XP in most cases you will need to install drivers manually.

In the future, we will assume that the computer has full package all drivers.

You need to go to the “Device Manager” (located in the “Hardware” tab, “System” window in the Control Panel) and remove the current audio driver. Or find “Multimedia Audio Controller” on your computer if there is no audio driver. Also clean (remove) all audio codecs on your computer. This can be done through the “Add or Remove Programs” section, Control Panel. Then restart the system. When working with Windows 7, the system will update everything missing drivers automatically, using Plug and Play technology.

If you chose to install manually, then you need to insert the disk with the drivers into the drive.

Apart from minor visual differences in the dialog box, the driver installation process is the same in all Windows versions(7, Vista and XP). We will look at the process of installing the driver on the XP operating system.

So, in the device manager window you need to find the “sound” or “multimedia” section. Double click to open properties. In the “Driver” tab, click the “Update” button. Answer the system’s question about the installation method: automatically or manually. Select manual installation and click Next.

In the dialog box, check the “Include next search location” checkbox and use the “browse” button to point to the drive. Click “Next” and the computer will search for the driver and install it. If the mouse does not work, and this can happen, you can complete the entire driver installation using the keyboard.

The system will notify you that the driver is installed and the system is ready for operation. The sound will be heard immediately or after the system is restarted. If none of the above still helps, you need to check the operation of the speakers again and proceed to step 7.

Step 7: Check BIOS settings

Sound loss may result incorrect settings BIOS settings. In the BIOS shell you will also have to operate only with the keyboard all the time, since the mouse is disabled in this mode. The integrated audio card can be disabled in the BIOS. You need to press the DEL button before the system boots (immediately after the computer starts). On some machines these are the F2, F12 or F10 keys. Make sure the switch is set to “Enabled” next to the motherboard in the BOIS device list. You need to turn on the audio card if the switch is set to “Disabled”.

And naturally, the reason for the lack of sound may be mechanical failure sound card. Try all the above methods before purchasing a new card.

Let me remind you that the sound on your computer can be adjusted using the keyboard using the F11, F12 keys.

I hope that the sound problem is completely solved by the simple instructions described in this article. If you still cannot restore the sound, contact a specialist for help.

Sound is a component without which it is impossible to imagine working or spending leisure time in the company of a computer. Modern PCs are capable of not only playing music and voice, but also recording and processing sound files. Connecting and setting up audio devices is not difficult, but inexperienced users may experience some difficulties. In this article we’ll talk about sound - how to properly connect and configure speakers and headphones, as well as solve possible problems.

Sound problems primarily arise due to user inattention when connecting various audio devices to the computer. The next thing you should pay attention to is the system audio settings, and then find out whether the culprits are outdated or damaged drivers, the service responsible for the sound, or virus programs. Let's start by checking that the speakers and headphones are connected correctly.

Columns

Speaker systems are divided into stereo, quad and surround sound speakers. It is not difficult to guess that the audio card must be equipped with the necessary ports, otherwise some speakers may simply not work.

Stereo

Everything is simple here. Stereo speakers have only one 3.5 jack connector and connect to the line output. Depending on the manufacturer, the sockets are different colors, so before use you need to read the instructions for the card, but usually it is the green connector.

Quadro

Such configurations are also easy to assemble. The front speakers are connected, as in the previous case, to the linear output, and the rear (rear) speakers to the jack "Rear". If you need to connect such a system to a card with 5.1 or 7.1, you can choose a black or gray connector.

Surround Sound

Such systems are a little more difficult to work with. Here you need to know which outputs to connect speakers for different purposes.

Green – linear output for front speakers;
Black – for the rear;
Yellow – for central and subwoofer;
Gray – for side ones in 7.1 configuration.

As stated above, colors may vary, so please read instructions before connecting.

Headphones

Headphones are divided into regular and combined - headsets. They also differ in type, characteristics and connection method and must be connected to a 3.5 jack line output or to a USB port.

Combination devices additionally equipped with a microphone may have two plugs. One (pink) is connected to the microphone input, and the second (green) is connected to the line output.

Wireless devices

When talking about such devices, we mean speakers and headphones that interact with a PC via Bluetooth technology. To connect them, you need an appropriate receiver, which is present in laptops by default, but for a computer, in the vast majority of cases, you will have to purchase a separate special adapter.

System Settings

If after correct connection There is still no sound from audio devices, then perhaps the problem lies in incorrect system settings. You can check the parameters using the appropriate system tool. Here you can adjust volume and recording levels, as well as other parameters.

Drivers, services and viruses

If all the settings are made correctly, but the computer remains mute, the drivers or a software failure may be to blame. Windows service Audio. To correct the situation, you must try to update the drivers and also restart the corresponding service. It is also worth thinking about the possible virus attack which could damage some system components responsible for sound. Scanning and treating the OS using special utilities will help here.

In order to start using audio devices connected to your computer, you must first turn on the sound on your PC if it is disabled. Let's figure out how to produce this operation on devices under Windows control 7.

You can turn on the sound on a computer on which Windows 7 is installed using the tools in this operating system or programs for controlling the audio adapter. Next, we will find out what the algorithm of actions is when using each of these methods, so that you can choose the one that is more convenient for yourself.

Method 1: Program to control the audio adapter

Most audio adapters (even those built into motherboard) are supplied by the developers special programs for sound control, which are installed with the drivers. Their function also includes activating and deactivating audio devices. Next, we will just figure out how to turn on sound using an application for controlling a sound card called VIA HD Audio, but these actions are performed in a similar way in.

Click "Start" and log in "Control Panel".

Navigate by item "Equipment and Sound" from the expanded list.

In the next window, click on the name "VIA HD Audio Deck".

In addition, the same tool can be launched via "Notification area", by clicking on the note-shaped icon that appears there.

The audio control program interface opens. Click on the button "Extended mode".

In the window that opens, go to the tab with the sound device you want to enable. If the button "Mute" active (blue), this means that the sound is muted. To activate it, click on this element.

After performing the specified action, the button should turn white. Also note that the slider "Volume" was not in the extreme left position. If this is the case, then you won't hear anything through the audio device. Drag this element to the right.

At this point, turning on sound using the VIA HD Audio Deck program can be considered complete.

Method 2: OS functionality

You can also turn on the sound via standard functionality operating room Windows systems 7. This is even easier to do than the method described above.

If you have done everything described above, but the sound still does not appear, most likely the problem is deeper and the standard activation will not help you. If so, check out our separate article on what to do when the sound doesn't work.

If everything is in order and the speakers produce sound, then in this case you can produce more fine tuning audio devices.

There are two ways to turn on sound on a computer running Windows 7. This is done using a program that serves sound card, or only built-in OS tools. Everyone can choose a more convenient method for themselves. These options are absolutely equivalent in their effectiveness and differ from each other only in the algorithm of actions.
