i observed the behavior, that the spotify app gets muted in volume control when changing the output.
I have 2 soundcards once I do any change on the output, spotify gets muted. all other applications remain in normal operation.
is that typical behavior or can I change it?
spotify is installed via snaps
I suggest you check information about the different active audio streams
pacmd list-sink-inputs
that will show if spotify is muted or suspended
but it might just be ‘corked’. Some music or video players will pause playback if Teamspeak or similar VOIP call is active
There is a PulseAudio module that can be unloaded so audio streams do not get corked
pacmd unload-module module-role-cork
That may stop spotify being muted when teamspeak is in use
That command does not permanently disable the module and it will be re-loaded if
the system is restarted.
The module can be permanently disabled permanently by editing PulseAudio configuration file /etc/pulse/default.pa
