Debian – How to disable sound modules in debian squeeze (solved)

audiodebiandebian-squeeze

The scenario, I have a debian squeeze xen virtual machine, only doing server tasks. On boot it autoloads sound modules despite blacklisting.

I know about modprobe -r, however ideally I'd prefer to stop them being loaded in the first place, hoping someone can suggest the 'debian way' to do this cleanly.

Rebuilding the kernel without sound support is not really a nice option.

What I've done so far…

root@debian:~# cat /etc/modprobe.d/snd-blacklist.conf
blacklist soundcore
root@debian:~# depmod -ae -F /boot/System.map-2.6.32-5-amd64
root@debian:~# update-initramfs -u -k `uname -r` -v

… and after a reboot …

root@debian:~# lsmod

Best Answer

Blacklist the snd module in the configuration. This is the core ALSA module.
