What's new : I can reproduce the problem on Ubuntu 20.04 live USB, so I'm sure the root cause is not a broken config on my side.
To summarize : Ubuntu 20.04 / Fedora 32.1 are affected. (Ubuntu 19.10 is not) - Rhythmbox 3.4.4 fully affected (wrong sink at start + output is switched to a RAOP sink with each new song) - Spotify is mildly affected : wrong sink at start, but after that you can play new song normally - Rhytmbox 3.4.3 (in Ubuntu 19.10) is lightly affected : wrong sink on 1st launched, but the last sink used is saved for next launch - VLC, Totem, Firefox, Chromium are unaffected Requirements to trigger the bug : 1 (maybe 2) RAOP (aka Airplay / AirTunes) sinks available on local network in addition to local soundcard. Steps to reproduce : $ sudo apt install pulseaudio-module-raop $ sudo apt install paprefs If needed, fix paprefs (which is broken in 20.04) $ sudo ln -s /usr/lib/pulse-13.99.1/ /usr/lib/pulse-13.99 optional, to monitor sinks used by rhythmbox : $ sudo apt install pavucontrol && pavucontrol Launch paprefs and check "Make discoverable Apple AirTunes soud devices available locally" Launch Rhythmbox, play a track, correct the sink, play another track (next button or direct choice), correct the sink, etc. As the issue has been abruptly dismissed upstream : https://gitlab.gnome.org/GNOME/rhythmbox/-/issues/1797#note_844963 (I assume the guy knows his job), you are my only hope here ! I know it's my fault, I should have stayed in Ubuntu 19.10 and wait 20.04.1, but I felt harassed by the updater popup reminder :) No, seriously I needed rhythmbox 3.4.4, to support my new phone. So what should I do now ? I understand there is some kind of middleware between pulseaudio and rhythmbox : gstreamer ? Could it be the "culprit" ? If yes, should I report a bug here https://gstreamer.freedesktop.org/bugs/ or downstream ? Is it possible to downgrade gstreamer ? ** Bug watch added: gitlab.gnome.org/GNOME/rhythmbox/-/issues #1797 https://gitlab.gnome.org/GNOME/rhythmbox/-/issues/1797 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to rhythmbox in Ubuntu. https://bugs.launchpad.net/bugs/1883902 Title: rhythmbox ignores pulseaudio default sink and outputs sound on random device Status in rhythmbox package in Ubuntu: New Bug description: Ubuntu 20.04 LTS rhythmbox: Installed: 3.4.4-1ubuntu2 Candidate: 3.4.4-1ubuntu2 What I expect to happen : When I launch rhythmbox, I expect it to use 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.
