Linux's System Beep

The system beep can be a very useful debugging tool when booting the system. however, once the Operating System has loaded, it is simply annoying. Fortunately there is a way to turn it off.

You need to edit the /etc/modprobe.d/blacklist file and add the line:

blacklist pcspkr

Reboot to enjoy your silence! Of course, enabling it again is a simple case of removing the line again.
