Read this whole message before doing any of it.

1. add an group entry to /etc/group (by hand or using groupadd)

        # groupadd audio

2. Add the users to the audio group (by editing /etc/group or by using
   usermod.  It's actually easier to hack the file than to use usermod.

3. ensure the audio devices are owned by group audio

        # chgrp audio /dev/audio /dev/dsp /dev/mixer #etc. etc.

0. On my debian systems the audio group already exists, and the audio
   devices are already owned by audio.  So all you have to do is 
   add a comma-separated list of usernames to the end of the audio
   line in /etc/group.  YKMV.
