While unloading/reloading does resolve the problem, once in a while 
though, sound is totally stuffed up after the
suspend/resume cycle and the modules cant be reloaded. Typically happens 
if I forget to unmute the
channels after resume and attempt to play something. At that point
trying to reload the modules is not possible (see the messages below). A
suspend/resume cycle resolves the problem.

[/root] modprobe -a snd-intel8x0
/lib/modules/2.4.20/kernel/sound/pci/snd-intel8x0.o: init_module: No
such device
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters.
        You may find more information in syslog or the output from dmesg
modprobe: insmod /lib/modules/2.4.20/kernel/sound/pci/snd-intel8x0.o failed
modprobe: insmod snd-intel8x0 failed

and in the syslog:
