Daniel, why do you think it's a gnome-media issue? Ubuntu has no gnome-media patch to the mixer and the same code works correctly in fedora, upstream also said it's probably an issue in your pulseaudio version
reassigning to pulseaudio for now but feel free to reassign back with some explanations which we could use to convince upstream if you think the issue is really a GNOME one
