Public bug reported: Upon clicking Sound within System Settings a crash occurs if the USB sound device is connected. If the USB sound device is removed the sound settings window can be opened. Sometimes the Sound Settings dialog CAN be opened but will crash when a USB output device is selected. Volume control works at times, doesn't at other times.
This bug has been reported (and confirmed) several times before (#1067700 , #1096424) but was ignored every time because no crash report was submitted. However, submitting the crash report FAILS on every computer I have tried (32bit, 64 bit - see below). To create your own crash file: Take any Ubuntu 12.10 installation. Plug in any USB sound card. Try to change its settings. Please do not close this report as well. Ignoring it will not solve the problem. ~$ lsb_release -rd Description: Ubuntu 12.10 Release: 12.10 sudo ubuntu-bug /var/crash/_usr_bin_gnome-control-center.1000.crash Error connecting to ConsoleKit: GDBus.Error:org.freedesktop.ConsoleKit.Manager.GeneralError: Unable to lookup session information for process '7264' .......ERROR: hook /usr/share/apport/package-hooks/source_gnome-control-center.py crashed: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/apport/report.py", line 197, in _run_hook symb['add_info'](report, ui) TypeError: add_info() takes exactly 1 positional argument (2 given) During handling of the above exception, another exception occurred: ....... etc. ** Affects: gnome-control-center (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1114358 Title: Gnome Sound Settings crashes with USB sound card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1114358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
