forcing a module to unload

Ashrack · 01-25-2006, 03:24 PM

GOt hibernation with SWSUP2 working flawlesly on my desktop.
Since am using a SND-CS46XX for alsa which doesn't properly support suspending, I had set the hibernate.conf to reload alsa when restoring from hibernation

Code:

/etc/init.d/alsa force-reload

which is kinda medssy

Now onto my questions:
when I do modprobe -r snd-cs46xx I always get the following error:

Code:

FATAL: Module snd_cs46xx is in use.

Is there a way to force the module to unload?
ps. I also tried

Code:

rmmod -f snd-cs46xx

but then the terminal just hangs.

You can only remove a module when the use count is zero. If you do an lsmod, you'll see the use count and a chain of dependent modules that have to be removed. Likely, even after you remove them, the count will be non-zero. You then need to kill all processes that use sound (like the mixer applet / volume control). Once the usage count is zero, you can "modprobe -r" or "rmmod" the module.
