I tried to get the PA-jack sink working last year - a week of fiddling
and I couldn't get it to stop getting kicked out by jack! I've ended
up using one soundcard for PA apps and another for jack apps. I would
have kicked PA out altogether were it not for one SDL-based game
(Braid) that wouldn't play nicely with ALSA.

I stumbled upon the same problem just a few days ago. All JACK clients
get realtime permissions just fine, only the PulseAudio JACK sink
doesn't. Even PulseAudio's JACK client thread, that should be created
somewhere in libjack, does not run with proper realtime scheduling.
Since no one on LAU seems to know the answer, I'm CC'ing the PulseAudio
list. Any help on this is much appreciated.
Cheers,
Dominic
