If I blacklist the pcspkr device in /etc/modprobe.d/blacklist, things are a little different:
No beep (or system alert sound) plays anymore, even with "play alert sounds" checked. Even clicking the little play buttons no longer plays the sound (neither beep nor the audio file). There is no more annoying beep on shutdown either. -- Annoying system beep plays instead of alert sound https://bugs.launchpad.net/bugs/301174 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
