Most any fresh Linux install, Debian in my specific case, automatically enables a multitude of wonderful high pitched beeps and tones for your listening pleasure. You might have noticed them by hitting a TAB on an invalid auto-complete, when you incorrectly login to GDM, or any of the other seemingly infinite ways to get an ear crunching BEEEEP.

To fix this issue you can go about disabling beeps in individual programs, but I have a better idea! Let's get the job done right and just blacklist the whole internal speaker to get rid of all beeps in all programs. Unless you are listening to motherboard beeps, who really need the internal speaker, anyways?

I use both modules as an example, just note the basic difference is that pcspkr is used in newer kernels. If one command does not work ('Module xxx does not exist' errors, etc), try the other.

Lets try to unload the (possibly) already running module.

1. # rmmod snd_pcsp
2. # rmmod pcspkr

Now we just need to make sure the module does not get loaded on system boot.

1. # echo 'blacklist snd_pcsp' >> /etc/modprobe.d/blacklist
2. # echo 'blacklist pcspkr' >> /etc/modprobe.d/blacklist
3. # reboot
