In my case, problem went away after killing pulseaudio and restarting it. Interestingly, while gnome-volume-control showed both audio sources (digital/analog), pavucontrol only listed the HDMI one, and even though gnome-volume-control showed analog as selected, muting the visible HDMI source in pavu, muted the gnome volume.
Killing pulse, and restarting, listed both sources in pavu, and the assertion stopped happening. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-media in Ubuntu. https://bugs.launchpad.net/bugs/628899 Title: Crash when testing speakers -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
