How would I go about blocking access to to the soundcard for certain users?

I want any users other than myself to be denied it, have looked at the user/group and soundcard settings in yast and can't see a way in there

I've looked at the audio entry in /etc/group and only my username is there:

audio: x :17:myusername (had to put spaces there or it showed up as a smiley)

It seems that whilst granting audio access is a simple matter, denying it needs digging deeper (I've read that some systems require audio access be granted to any users added, that sort of setup would also work for me)

I'm running suse 10.2 64-bit, any help appreciated
