Loud buzz/beep at errors

http://forums.opensuse.org – I've just installed openSUSE 11.2 on my new Dell Precision laptop. The computer speakers (I think it's the ordinary ones, not the buzzer, but cannot be sure) make a loud buzzing noise when I do something "wrong". This may be pressing Ctrl-Alt-Backspace, pressing backspace when there is no character to delete, etc. I've managed to remove some of the beeps/buzzes, after doing the following: - Add the line "set bell-style none" in /etc/inputrc - Remove the kernel module pcspkr - Add the line "setterm -blength 0" in ~./profile - Muted PC Beep and PCM in the mixer But still I get a loud buzz when pressing Ctrl-Alt-Backspace (and probably due to other actions as well), even when all sound is muted in the mixer. How can I remove this annoying sound? (Distributions)
