Same bug apparently and i have ubuntu focal kernel. In my case the next command
this fix partially my problem, because my audio is set to null in sound, but i
can listen it:
pacmd set-card-profile 0 output:hdmi-stereo
Note i have this problem for a long time, but with ubuntu focal is worse
than ever. I can not find a good permanent solution.
Only in pavucontrol i can see my HDMI Audio and this is what i can see
when i can lisent something:
