I can't reproduce this. After signing out / signing in, I launch foobar2000 and begin playing audio without issue. Is there some other type of audio or application you're using that I could also test?
Any warning signs in Device Manager? I'm assuming you've tried to reinstall the driver, correct?
What fixes the no audio for you? Restarting?
Which Windows build?
I'm using
the VLC media player for testing, but no other audio applications work either. No warning signs in device manager, everything appears to be working correctly. I have tried reinstalling the driver, yes, it makes no difference. So far, the only thing I've found that fixes the audio issue is restarting. As to Windows version, it's Windows 10 Pro x64 [Version 10.0.18362.720].
I don't know if it helps, but I've also found the same thing happens if I connect to the machine using Remote Desktop. Once I've connected to it via remote desktop, logging in at the machine itself means no audio until I restart. I don't know if that provides another potential problem vector, or if it's the same underlying issue, but I thought I'd report it as well.
