How to fix the computer headset has no sound.
-
1. There is no sound from the earphones, first check if there is any problem with the earphones. Plug in someone else's banquet and take a look.
2. Open the control panel - sound audio device - see if the volume of the device is muted, turn on advanced to see if the first two items are muted.
Right-click the desktop speaker to turn on the volume control and see if mute is selected for the first two items.
3Check the sound card driver, the general computer has no sound mainly because of the sound card driver, check the method: Device Manager - Sound ** Game Controller, see if this item has an exclamation mark or question mark, if there is a reinstall driver, if you don't know the model of the sound card, you can directly download the universal driver. There is no exclamation mark and there is a small speaker in the lower right corner of the desktop, indicating that the driver is fine.
4. If all of the above is possible, it is possible that the BIOS is set to disable the sound card, but no one will be okay to set this thing there, and I believe you will not set it up. I don't know how to either. So it's very unlikely.
5. Reloading system.
6. If the reinstallation system does not solve the problem.
It's just that there is a problem with the sound card (onboard sound card).
