After changing Windows 11 to Windows 10, the sound disappeared, I returned to Windows 11 again, there was no sound, the driver does not find it, I tried everything, please send the real driver to my mail tvoyo.schaste.98@inbox.ru @ChuwiService
I had the same problem, i had to go download fhe drivers from mircosoft for the sound drivers but there free so its pretty easy to download and install they will give you instructions on how to do it
You can get the latest drivers from the Windows Catalog:
