[LAU] pulseaudio-module-jack realtime issue

Hey all, I am experiencing some clicking/popping noises when running Jack on my both my internal and external USB interface. Oddly this did not coincide with the usual culprit, XRuns. I tracked it down to some errors in the system logs.

I am fairly new to the pulseaudio-module-jack package(Ubuntu) that supplys module-jack-sink and module-jack-source for Pulse/Jack integration. Any help is appreciated, Brian
