crvi : did you use RAOP sink as networks sinks ? I don't know if it matters, but my 2 networks sinks are both RAOP.
Anyway, I have some more information : I can totally reproduce the problem with latest Fedora Live USB (Fedora-WS-Live-32-1-6), so it's not OS specific. I also tried Ubuntu 19.10 on live USB : the problem is not here. To be specific, in this situation : the 1st time I launch rhythmbox, it ignores my default sink. But with pavucontrol I can remap it to my local sink (my soundcard). Then I quit and relaunch rhythmbox : this time it remembers the last sink used and outputs sound on my local soundcard. My humble analysis : - it's probably an upstream problem - rhythmbox never took the default sink defined in pulseaudio into account - In version 3.4.3 and before, rhythmbox remembers last sink used and reconnects to it for next launch - this "save" function broke in 3.4.4 - specific conditions to trigger the problem are still to be defined, RAOP sinks may have a role -- 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.
