GemiBook Pro , Mic don't work on Windows10 20H2


After I updated my Gemibook to Windows10 20H2, digital mic inside stops working.
I could not roll back to older version Windows 10 as I did not make recovery file.

Does someone know how to resolve this issue?

That is strange… Is your drivers up to date? Check in the device manager.

Thanks Orion,

Yes, I checked device manager, but no <!> mark found. Drivers seems up to date.
Before updating to 20H2, mic works fine.
