Here is how to disable the system beep in Ubuntu:

Step 3: To regain the System Beep type in this command: sudo modprobe pcspk
There you go an easy step by step way of turning off terminal beep!

Hey Ryan,
This will work in almost any Linux distribution, but the beep will return if you reboot the system. A better way is to edit /etc/modprobe.d/blacklist and add “blacklist pcspkr” to the file.
If you want to disable it temporarily, it’s better to use “modprobe -r” than “rmmod” which is deprecated.
