That sounds wrong. I would assume that the access to audio is allowed
to whoever owns the console, so the check should not be whether the code
runs as root or foo but if the current user for that code has those
permissions.
I.e. if user foo uses the console but user bar ssh to the box and
starts a new domain, that check would just not work.
On the other hand if you are logged on the console as root I don't
see why that test should be applied.
Can't you extract from SELinux if you have the access instead ?
And pulseaudio should not crash in the first place !
