In that case you have to remove the module that uses snd_pcm (probably
snd_pcm_oss) before you can remove snd_pcm.

There is some problem with the driver, therefore it is important to have
more details about what is going on when the modules are loaded. Try to
unload all snd* modules so that "lsmod | grep snd" returns no output.
(If this is not possible then you should find out which modules are the
blockers to help isolate the problem.)

If you can unload all sound modules, run

modprobe -v snd_via82xx snd_pcm_oss snd_seq

as root and post the output here.
