Hi,
How did you get Microsoft driver after uninstall Conexant drivers?
Did you just uninstall thoose drivers, reboot and windows proposed "microsoft audio drivers" afterth restart?
Nearly.
device manager -> audio, video and game controller -> Conexant SmartAudio HD
-> right click -> uninstall device, but activate "uninstall driver"
you need to reboot on request after some time (wait!)
after reboot M$ driver is installed
BUT in the meantime Windoze installed the Conexant driver automaticly again (8.66.77.57 in my case).
It works fine. No BSOD etc. So I will keep it
PS: I am on 20H2 since yesterday
