Since a lot of people work in runlevel 3 the previous tip may not work.

So I’ve searched for other solutions found another way of disabling system beep (on tab completion).

Just edit /etc/inputrc

vi /etc/inputrc

and uncomment following line:

# do not bell on tab-completion
set bell-style none

Then after next login system beep on tab completion will be disabled system-wide.

And another one:

as root type:

rmmod pcspkr

This one will remove the module responsible for playing sound on system speaker.


blacklist pcspkr
in /etc/modprobe.d/blacklist

Should disable the module too, but it is not working for me under CentOS 5 – submitted as bug.

Another one (Hardware):

If you have PC simply open the case and unplug speaker cable from the motherboard.

NOTE: PC speaker could be very usefull when troubleshooting problems so this option is not really recommended.

OR search in your BIOS for option to disable it.
