I've found a way to 'handle' the bug, and make changes as I wished, and have my sound back.
1 - To access the control-center. # sudo gnome-control-center There you make the changes, and your user stills affected. 2 - To have the sound back... # sudo apt-get install dkms #sudo reboot After reboot the sound must be back. This worked... Hope help the other eleven people with the same problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/932446 Title: [sound-nua] gnome-control-center crashed with SIGSEGV in gtk_tree_model_get_valist() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/932446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
