When you turn on your computer or laptop while the operating system boots, music plays. But if you turn on the device, but do not hear anything, or try to listen to your favorite song or watch a movie, but you cannot do it, then the natural question "why there is no sound on the computer" arises.
Instructions
Step 1
The reason why there is no sound on a computer or laptop can only be a breakdown of sound equipment or a software malfunction.
Step 2
To tune the sound, first check to see if it is muted. A small speaker appears in the lower right corner of the taskbar. If you see a red crossed out circle, then you just need to click on it and turn on the audio signal.
Step 3
Also, the sound on the computer can be turned down to a minimum. Click on the same speaker and move the volume slider up. Check if the audio is muted in your program. If there is sound in other applications, then you just need to enable it in a specific program.
Step 4
If the sound does not work, see if the speaker wires are plugged into the correct connectors. Check if the power of the speakers is turned on, as well as the on / off switch, if the sound level is lowered to zero.
Step 5
If everything is fine with the speakers, and the sound on the computer has disappeared, try restarting the device. There may have been a failure to download the software.
Step 6
Open the hardware manager via the Start> My Computer panel. Check if the malfunction icon next to the audio device is lit. If it is, fix the problem.
Step 7
Try reinstalling your sound card driver. To do this, download it from the manufacturer's official website. The device name can be viewed through the hardware manager. You can update drivers in automatic mode, to do this, click on the corresponding device in the manager and select the desired tab.
Step 8
Some parts of the computer sometimes break. Usually this does not affect the operation of the entire system, but if for some reason the sound on the computer disappears, the whole matter may be in a damaged sound card. You can try to replace it with a new one, and in order not to spend money, before that you can ask a friend to test a spare part.
Step 9
Remember when the sound stopped working. Perhaps after updating the operating system or installing a new program? In this case, you can state a conflict in the operation of the software. Uninstall new applications or try restoring the system to the latest working version. In Windows 7, this feature can be found in the "Start -> All Programs -> Accessories -> System Tools -> System Restore" panel.
Step 10
If all of the above steps do not help restore the sound that was missing on the computer, try reinstalling the operating system. Then, first of all, install the drivers on the motherboard and sound. If the audio signal appears, after installing the next utility, check if it has disappeared. The reason why there is no sound on the computer, in this case, may be hardware or software conflicts.
Step 11
If, after all the manipulations, the sound on the laptop or computer still does not work, contact the service center. Perhaps the specialists will solve your problem faster.
