Public bug reported:

in gnome settings audio section does not see any sound card. if i run
alsamixer it can detect the sound card and all works fine. in gnome
sound settings everything seems to be disabled.

I have excatly same problem on PC where configuration is completely
different than my laptops one.

All the problems started recently, after upgrading to 19.04 some time
later one of the updates destroyed all sound
