I need to completely disable audio on this system. It's klunky.
How to do?

(the audio is a Realtek 861 on a Toshiba Satellite A105).

Thanks in advance.

As root, use 'modprobe -r' to remove the sound module from
memory. First use 'lsmod' to see the list of modules:

# lsmod
Module Size Used by Not tainted
ppp_deflate 2776 0 (autoclean)
zlib_deflate 16760 0 (autoclean) [ppp_deflate]
snd-realtek-861 8150 0 (autoclean) [...]
[...]

# modprobe -r snd-realtek-861

This is just an example; the actual name of your sound module
will probably be different.

Why?

How exactly to do this depends on what sound system you use. Old
obsoleted sound system OSS or new ALSA.

Remove sound modules and sound driver for your Realtek.
Then noone can use tha sound.

Remove esd or rats running in your graphical environment (GNOME or
KDE). Then yoiu won't get any sound, but other still can use sound.

Good Luck

When some sound effect plays - say, in Gaim - there is some recursive
anomaly that causes the sound affect to keep on playing until I reboot or
do a "shutdown now".

I'm not clear on how to "remove sound modules and sound driver" other than
rebuilding the kernel - which is an option for several weeks in the
future; but not a quick one for me.

In the FreeBSD world I need to tell the system what modules to load on the
boot; and - try not to be shocked - but building a new kernel is far more
straightforward than it is in Linux... but surely, a smaller world of
equipment is supported (which brought me to Debian - Atheros wireless
works better in Linux than in FreeBSD... albeit using a closed-source
driver.)

I used to have this problem too. I'm using Sarge with kernel 2.4.27 (386).

Whenever I built my own kernel from source, I got an effect where sounds
would repeat 3-15 times, so I added the name of my sound module to a
file in /etc/hotplug/blacklist.d/ to prevent it from loading.

I eventually solved the problem by installing a binary kernel package
from debian.org.

Evidently, there is a bug where some systems can't build some sound
modules correctly. Either that, or the userspace drivers need to be
rebuilt along with the kernel modules. I've been wondering about this
problem for months.

So, what is the sound driver for you system?

Does it really repeat forever, or might it just repeat 60 times?

To test if sound is working correctly after a kernel installation and
reboot, I always do this:

cd /usr/share/apps/kbounce/sounds
cp death.au /dev/audio

A single popping sound should be emitted; what does this do for you?
