I’m not sure why but the system beep seems to be one of the favorite sounds in Ubuntu. I hear it often when I mistype something at the terminal, when I’m accidently clicking the wrong thing, or sometimes if I just accidently hold down a key a bit longer then I should.

I’ve found the system beep to be very annoying and I’m guessing that many others do as well. The system beep is the loud, annoying noise that comes from inside your computer and is not played in the speakers.

If you are like me and find it to be more of an anoyance then something that is helpful you might have been looking for the setting to shut it off and failed to find it thus far.

Open a Terminal and type (or copy and paste the following):

sudo rmmod pcspkr

You will be prompted for your password and it will take only a second for the command to run. If it shows your username again on the Terminal then you’ve successfuly removed the system beep.
