It looks like you are on the right track.  The permanent solution I use
is to create a new group "sound", and add any users needing access to
audio hardware to the new group.  Then, in /etc/security/console.perms,
edit sound class permissions as follows:
<console>  0660 <sound>      0660 root.sound

This will allow all users in group "sound" to access all audio devices
(as defined in the upper portion of /etc/security/console.perms) on each
subsequent reboot.
