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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883902 Title: rhythmbox ignores pulseaudio default sink and outputs sound on random device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/1883902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
