There was an update today to the gnome-control-center and more specifically landing the new sound menu in Precise. However when I try to launch sound setting, the window disappers immediately without any warning. So I launched the gnome-control-center from the terminal, and then launched the sound settings from it. It again disappers but I get the following message in the terminal. 4 profiles supported on port Analog Output 6 profiles supported on port Internal Microphone 2 profiles supported on port Analog Input / Microphone / Microphone 2 profiles supported on port Analog Input / Microphone / Line In 6 profiles supported on port Microphone 4 profiles supported on port HDMI / DisplayPort 1 profiles supported on port Analog Input / Microphone / Microphone 1 profiles supported on port Analog Input / Microphone / Line In 1 profiles supported on port Analog Input / Microphone / Microphone 1 profiles supported on port Analog Input / Microphone / Line In 1 profiles supported on port Analog Input / Microphone / Microphone 1 profiles supported on port Analog Input / Microphone / Line In 1 profiles supported on port Analog Input / Microphone / Microphone 1 profiles supported on port Analog Input / Microphone / Line In 0 profiles supported on port Analog Input / Microphone / Microphone 0 profiles supported on port Analog Input / Microphone / Line In device->priv->disable_profile_swapping = 1 Segmentation fault (core dumped) ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: gnome-control-center 1:3.2.2-2ubuntu7 ProcVersionSignature: Ubuntu 3.2.0-15.24-generic-pae 3.2.5 Uname: Linux 3.2.0-15-generic-pae i686 ApportVersion: 1.91-0ubuntu1 Architecture: i386 Date: Fri Feb 10 18:34:36 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Alpha i386 (20120116.2) ProcEnviron: PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: gnome-control-center UpgradeStatus: Upgraded to precise on 2012-02-03 (6 days ago) usr_lib_gnome-control-center: activity-log-manager-control-center 0.9.0.1-0ubuntu1 deja-dup 21.2-0ubuntu4 gnome-bluetooth 3.2.2-0ubuntu1 indicator-datetime 0.3.1-0ubuntu5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/930289/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
