rhythmbox ignores pulseaudio default sink and outputs sound on random device
-
Ubuntu 20.04 LTS -
rhythmbox: 3.4.4-1ubuntu2
What I expect to happen :
When I launch rhythmbox, I expect it uses the default pulseaudio sink. (Which can be defined in pavucontrol or with set-default-sink in /etc/pulse/default.pa ).
What happened instead :
When I launch rhythmbox, it outputs sound to a random device (in my case : either a RAOP sink in my living-room, or another RAOP sink in my kitchen. Never my local soundcard)
If I correct the output sink (with pavucontrol or pactl) the problem is fixed... until I quit and restart rhythmbox.
I did not have this problem with Ubuntu 19.10 / Rhythmbox 3.4.3-2ubuntu1
In 20.04 : -> Spotify (snap store version 1.1.26.501.gbe11e53b-15) has the same problem -> others apps I tested (Firefox, Chromium, VLC, Totem) do not have the problem
I already tried to delete $HOME/.config/pulse with no improvement.
