@Guy Taylor, as a workaround you can use the "pavucontrol" application, available in the repositories as the "pavucontrol" package.
@Seb128, looking from the stack trace, it does not look like PulseAudio's client API is involved in the infinite recursion. I'm marking this as invalid for PulseAudio. Conor might have meant bug 978109 - without that, maybe this infinite recursion bug would not have surfaced. ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete ** Changed in: pulseaudio (Ubuntu) Status: Incomplete => Invalid -- 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/963457 Title: [soundnua]: gnome-control-center crashed with SIGSEGV in g_mutex_lock() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/963457/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
