Forbid user control over ALSA [disable PolicyKit?]

They should be able to use flash etc, but not with sound.
If I allow them to use flash at the moment and they use something that
produce sound (i.e. youtube) that sound will disrupt the stream from mpd.
Exactly that example does not work in real life as my alsa does not have
mixing, but the general idea applies.
I want to allow the user to use whatever applications their heart desire -
but not communicate with ALSA and the like.
While poking around I found some things related to PolicyKit, I figured that
it may or may not be involved but since I'm completely unfamiliar with
PolicyKit and HAL I have no idea if I'm right in that PolicyKit is the bad
guy. Sorry if that is completely erronous.
