Rhythmbox uses ```autoaudiosink``` gstreamer plugin for outputting audio, which means Rhythmbox outsources the audio sink selection process to gstreamer. So, test your bug with the following command first.
``` $ gst-launch-1.0 -v -m audiotestsrc ! audioconvert ! audioresample ! autoaudiosink ``` This plays a audio tone on the audio sink "automatically" selected by gstreamer ```autoaudiosink``` plugin. If the same random device sink selection happens, the issue could be with ```autoaudiosink``` gstreamer plugin, and not Rhythmbox. https://gstreamer.freedesktop.org/documentation/frequently-asked- questions/using.html?gi-language=c should help. -- 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
