Affects me too. Ubuntu 12.10, 64 bit, Gnome Shell 3.6. It happened right after installation in Unity, then started working when I installed and switched to Gnome Shell. Today, I found the Sound Settings are broken again.
Same behaviour as for Def Sum. Crashes immediately after clicking on it. Works when I unplug my USB card, but shows no card installed (only a dummy device). I tried fore-reloading alsa and plugging the USB card back in, but then it crashes again. Any help would be highly appreciated. I really really want to configure my sound settings. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067700 Title: Sound Settings crashes when USB audio mixer selected as input To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1067700/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
