Introduction

The computer often seems to make beep noises at various times, whether we want them or not. They come from various sources, and as such, you may be able to configure if or when they occur.

They are often caused by the BIOS (Basic Input/Output System), the OS (Operating System), the DE (Desktop Environment), or other software programs. The BIOS is a particularly troublesome problem because it is kept inside an EPROM chip on the motherboard, and unless have a setting you can adjust in the BIOS setup or you wish to attempt to reprogram that chip with the proper light source, it is not likely you will be able to change it at all. That beep sound is not addressed here.

However, everything else which can cause a sound to come out of the computer case speaker can be handled with the suggestions below.

Note: One should also note that the option of turning off a particular instance of the sound, while leaving the others operational, is possible if one can identify which portion of the environment is the source of the particular sound generation. This can make a very customized selection of attention-getting sounds possible. Please feel free to add your findings to this wiki page when you find particular examples of settings combinations which may be useful for other users.

Globally

  • You can completely disable the PC speaker module at startup by adding !pcspkr to the MODULES array in /etc/rc.conf:
MODULES=( ... !pcspkr ... )
  • If lsmod | grep snd-pcsp returns something, add !snd-pcsp:
MODULES=( ... !snd-pcsp ... )

In this forum thread, it's recommended to add both to your /etc/rc.conf.

Locally

In X

$ xset -b

You can add this command to a startup file, such as ~/.xinitrc, to disable it every time X starts.

In console

$ setterm -blength 0

Similarly you can add it to ~/.bashrc.

  • Another way is to add this line to ~/.inputrc:
set bell-style none

Using ALSA

  • Try muting the PC Speaker:
$ amixer set 'PC Speaker' 0% mute

For certain sound cards, it is the PC Beep:

$ amixer set 'PC Beep' 0% mute

You can also use alsamixer for a console GUI

$ alsamixer

Scroll to PC beep and press 'M' to mute. Save your alsa settings:

# alsactl store

In order for this method to work, you must add alsa to the list of daemons in /etc/rc.conf
