Edit: Fixed by adding
environment.systemPackages = [ ...
kdePackages.plasma-pa
]
I am unable to select default output or input devices on the system level anymore (Such as through the volume mixer widget in the panel), but if the app (discord) itself includes those controls, I am able to choose in its menu. I would like to get the volume mixer back
Under “System Settings” → “Audio”:
