Not sure whether you really want that. Anyway, the manuals from Red
Hat cover PAM a bit. And have a look at "man 5 console.perms".

No, that's common misconception of a security feature. Would you
want network users being able to monitor your microphone or play
back an MP3 file at full volume 4:00 a.m. when you're sleeping?

The alternative would be to adjust the permissions to let a group of
users access the audio device at the same time. Not sure whether you
would like it when one user plays with the mixer while you are
listening to a stream.
