Public bug reported:
This wasn't present in 19.04:
When returning from hibernate, audio devices is changed to hdmi (gp104 device),
which is not even plugged in. When playing audio and changing volume one has to
go into volume settings or pavucontrol to change the output/controlled device
back to "Line out".
Disabling "module-switch-on-port-available" is not an option because that
disable automatic switching to headphone output.
I've tried disabling the gp104 device in pavucontrol, but this has no effect,
it keeps switching to it.
This is not specific to the nvidia driver's gp104 hdmi output though, to be
clear, because the same thing happened when I had pulseaudio-dlna active -- it
switched to those devices after wake, which was even worse because playing
audio on the computer after a wake-from-sleep kept launching my
chromecast/other dlna devices in my apartment.
