Disable System Speaker in Ubuntu

[WobbleWobble]

I have a Dell Inspiron 8600 laptop and am using Ubuntu 5.04. When I'm in a terminal and do things certain actions like press "tab" to autocomplete and get more than one choice, it makes my system speaker beep. I know it's normal but I'd like to disable it since I use my laptop in lectures often. I tried muting everything possible with no avail and yes, my regular sounds get muted with that.

This is configurable at a bunch of places, including:

* Your shell should have an option about when it beeps

* X can be configured to make the console beep do different things, as in "xset b off"

* A kernel-level disable of the speaker device; on NetBSD the device is called pcppi, but I don't know what a linux kernel would call it
