Hey, Is there a way to control the PC-speaker with the Linux kernel 2.2?
I want to disable it.
I guy told me that with this assembly code I can disable it:
in al , 97
and al,253
out 97,al
Linux 2.4 will have any syscall to do this?
Thanks

Try this on the console:
setterm -blength 0
no assembly required. :)

Yes, and my xterm still beeps - if I make that go away then something
else will beep.
Somebody posted a patch to do a global disable of the speaker some time
back, and I wish that the patch were generally available. The result of
not having the global disable is an office full of beeping computers.
How does this look:
cat 0 >/proc/sys/dev/speaker/beep

Right, I see what you mean. Disabling the beep is one thing I always
do, and it requires a few differnt steps, like "xset b off" for xterms
and so on. It would be nice to switch it off in one place and be done
with it.

This looks good to me. As far as I can tell, it looks like the beep
is generated by kd_mksound, which is a function pointer that usually
points to drivers/char/vt.c:_kd_mksound(). Can anyone verify this?
It doesn't look to hard to write a sysctl driver that would change the
function pointer to something quieter. Is this what patch did?
