The pulse-rt group should not be needed with policy-kit (group based
privs and policykit based privs are two separate systems AFAIK) but I
think your approach is generally correct and that starting pulse as root
is *not* the right solution to this problem.

It's possibly that you have been caught by a permissions problem that
was in cooker due to udev a while back (but it's been solved for a while).

Come on to #mandriva-cooker IRC and I'll try and help you debug this now
that it's apparent that the hardware is physically working :)
