No sound in windows domain's users

I’ve installed OpenSUSE 11.0 in 27 PCs where I work and now I found out the audio doesn’t work when logged in with the domain users.

when root, the audio works fine. when users, the Mixer doesn’t appear in loggon and if I open it, it’s like there’s no soundcard.

What should I do?
(the users are in windows domain, please don’t tell me to use that audio group config…)

An option could be that users are not added in the proper groups.Maybe is that but im not sure tbh

There are no users to group… they’re all in windows domain…
