How to take out the system built-in beeper in Linux
By admin | December 18, 2009
Usually the system beeper (not to be confused with speakers) can be a rather useful tool in informing or alerting the user. Sometimes however, the beeper can be just plain annoying, especially if you already know what you are doing. For example, it is very annoying to have a laptop suddenly start beeping in the middle or a presentation or on a subway train. Here’s how to disable it to avoid such embarrassment.
To permanently disable:
Execute in a shell (Applications >> Terminal):
echo -e "\nblacklist pcspkr\c" >> /etc/modprobe.d/blacklist.conf
To temporarily disable:
Execute in a shell (Applications >> Terminal):
sudo modprobe -r pcspkr

Very good players are always beating the world record for Drift Boss! As you can see in the video tutorial on this page, scores can get very high. The current record is over 63,000. Are you sure you can beat it?

Thanks for this guide. I had the same issue with the built-in beeper on an older machine at home, and the modprobe blacklist approach described here worked well for me too. Clear and practical explanation.

Thanks for the detailed walkthrough. That constant startup beep had been driving me crazy on my old workstation, and following these steps finally silenced it for good. Clear and easy to follow even for a Linux beginner.
