If you’re like me, you start getting real annoyed, real fast at the system beep that insists on beeping far to often. This system beep emits not from your laptop speakers, but from that deep, dank recesses of ancient pc technology that is a little speaker designed only to beep annoyingly. Short of ripping it out, here’s how to disable it.
You can disable this by editing a file and entering two simple lines.
And then add:
#silly speaker beep
Save your file and the speaker beep will be gone when you reboot.
If you don’t want to wait until a reboot, simply type:
sudo rmmod pcspkr
To your success,
