Stopping Debian beeps

This drove me nuts, luckily there are a few ways to disable it it:

1. Add the following to the Gnome session manager (or equivalent)

xset b off

2. Blacklist the device

echo "install pcspkr true" >> /etc/modprobe.d/blacklist

The former only stops be beeps while in X, the latter disables the PC speaker entierly. For the life of me I can’t work out why the beep is still on by default.
