PulseAudio -> JACK connection in Oneiric

[David Henningsson]

I gave the PulseAudio/JACK integration a quick check in Ubuntu 11.10, 
basically I started banshee playing through PulseAudio, and wanted it to 
play to JACK.

I had these obstacles to overcome:

1) There is still a pasuspender wrapper script when starting qjackctl! 
Instead of starting "qjackctl", you'll have to start 
"/usr/lib/qjackctl/qjackctl.real" instead. (This is particularly 
annoying as I remember having removed a similar script earlier, but 
apparently it has been re-added by Alessio?)

2) When starting JACK server (from qjackctl), sound from PulseAudio 
stops, but it complains that the sound device is still in use. This 
seems to be a timing issue. Just stop and start the server a second time 
and it works.

3) I used pavucontrol to reroute Banshee's audio stream, so that in 
pulseaudio, Banshee's is routed to the JACK sink.
