How to add my useraccount in audio group?

I have installed openSUSE 11.1 with kde.
But i can’t hear login sound.
cat /etc/group doesn’t display my useraccount with audio: group.
How would i add useraccount with audio group?
What’s the command?

Having your user in group may not solve that problem, as it could be another (unknown to me) reason. Still, to add your user to group audio is easy from the GUI. You can follow step-6 in this guide: SDB:AudioTroubleshooting - openSUSE - step6 how to fix a permissions problem

Adding useraccount to audio group solved the problem.
