Why did the sound of my computer suddenly stop so many times in the past two days, and then it resta

First of all, the computer is silent, but sometimes the problem is more complicated, involving both hardware and software problems. Therefore, it is necessary to find out the cause first, see if the software or hardware is malfunctioning, and then prescribe the right medicine for the problem. We must not mess around for unknown reasons, because if we don't do it, the system will be paralyzed, and the trouble will be big.

1. Check whether the sound card, cable, speaker and other equipment are connected normally; Run anti-virus software for anti-virus; 2. Right-click "My Computer" --Properties--Hardware"--Device Manager", and open "Sound, ** and Game Controller" for any problems, that is, see if there is ** in front"? "If so, reinstall the driver for this device to solve the problem; 3. When there is sound but no speaker, open the control panel --- the sound and the volume --- the device, and put a check mark before "put the volume icon into the taskbar"; 4. When there is no sound and no speaker, open the control panel--- Add and remove programs--- add and delete Windows components, put a check mark in front of "Accessories and Tools", click "Next", and then, shut down and restart, the system will prompt you to install new hardware, follow the prompts to install; 5. Uninstall the sound card driver, reinstall or upgrade the audio driver; 6. When the sound card driver is installed, the prompt "AC chip cannot be found" appears, it may be that the computer is poisoned, or the sound card driver has been deleted by mistake due to illegal operation, or there is an internal software conflict. The solution is to reinstall the system and drivers.

7. Simply ignore it, wait for a period of time after shutting down and then turn it back on, sometimes the sound problem will solve itself. You might as well give it a try.

1. Check your speaker cable to make sure the connection is normal. 2. Right-click on my computer's Properties Hardware Device Manager to see if there is a yellow "" in front of the device? "Or"!

If so, please reinstall the drivers for this device. 3. When the small speaker is not visible in the lower right corner, open the control panel Sound & **Device Volume, and put a check mark in front of "Put the volume icon into the taskbar". 4. Reinstall or upgrade the sound card driver, if you can't find the driver, you can update the sound card driver.

address it automatically recognizes the driver, installs it automatically, and is up-to-date. Sometimes you can restart your computer and it will be back to normal, I've tried it many times, but I don't know why it's back to normal! Hehe!!

Either the headphone cable is broken, you can check it, or the sound card driver is not normal, you can use the driver life to update,

The data cable of your speaker is not in good contact,It's good to change a good wire,It should be somewhere to break the wire,Or the quality of the data cable is too poor and there is a place to touch the line。

If there is a problem with the audio device settings, open the speaker manager and close the front jack.

Win7 and Win10 are prone to this kind of problem because of the vulnerability in the system itself, not the problem of the device.

The headphone connector or computer audio interface is broken.

It may be that some features are turned off when you are using it, and this one is harmless!
