I had a quick look at the pactl list output and noticed the following things:
1) You seem to be running the cinnamon desktop. This usually shouldn't matter; but in this case actually it can. So I'm wondering if this is also reproducible from a clean Live-CD of, well, saucy/trusty at this point, and Ubuntu with unity desktop? 2) Only the Maudio card is present; is your onboard card disabled? If so, is it related to you actually plugging it in while the sound settings dialog is open? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1131220 Title: [soundnua]: gnome-control-center crashed with SIGSEGV in gvc_mixer_control_lookup_device_from_stream() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1131220/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
