Re: disable beep for wall command
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.
