sound not working

Hi, thank you for that information. In this case, I suggest doing a system restore, wherein it will restore the PC, where it was working properly. To do that, kindly follow the steps below:

Press the Windows key + R, then type in:

rstrui

Then hit OK.

Follow the prompts and select the time and date when the PC is working fine.

Follow the prompts again until it restores.

If none will work from the above solutions work, I suggest doing an in-place upgrade wherein it will update the device to the latest version and repair all issues without deleting any files.
