This is about the only persistent problem I have had with my Pi4, which I use as a daily driver. The audio stopped working (again) after today's update. It still works if I use VLC and manually change the audio, so it is not a hardware issue. The only hardware oddity is that it is a DVI monitor using a HDMI-DVI converter. The converter is the same one I have been using since September(?, since I got the Pi4).
I have tried resetting with raspi-config to headphones and reboot, no go.
I have tried the gui under audio icon, it boots to analog, no go.
I have tried sudo amixer cset numid=3 1, no go (with and without reboot).
Any bets what is off this time?
