Re: disable beep for wall command

[Iuri Guilherme dos Santos Martins <iuri.guilherme.dev@gmail.com>]

What's making that horrible beep is the calling of the funtion 
sigaction() with the first parameter being SIGALRM, and then it being 
called the function alarm().
As we said, disabling your pc beep disables this, as disabling only the 
wall will not solve your problem (other programs will also beep the 
whole time).
If your ALSA mixer does not have this (are you sure?), then maybe your 
sound card is controlled by other system that's not ALSA. In that case 
the gnome-volume-control may or may not have the pc beep option, but 
check the preferences again.
