Public bug reported:
For last couple of months I've been using 20.04 sound OK on my Dell
laptop but since last apt update/upgrade two strange things happened:
1. the HDMI Out sound device completely disappeared and I can't select
it in pavucontrol/GNOME/any application
2. when I use Built-In Audio Analog Stereo > Headphones , it works for
only few seconds and then stops.
Thus the only sound that remains working is Built-In Audio Analog Stereo >
Speakers (cheesy built-in speakers). This is what worked all the time during
the ubuntu-bug test.
Please rollback!
