For me, it’s very embarrassing the beep sound on Fedora Linux, especially when I’m on the virtual console. So, the first thing that I do after install a Linux Operating System, is to disable the beep sound.
With the root rights, add the pcspkr module to the modprobe blacklist file:
… and add the lines below to the file:
# turn off system beep on Linux
After reboot the system, check if the pcspkr module was loaded:
lsmod | grep pcspkr
