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.

>Cannot use real-time scheduling (RR/75)(1: Operation not permitted)<

error >Cannot use real-time scheduling (RR/75)(1: Operation not
permitted)<

error >AcquireRealTime error<


Looks like pulse is having trouble with realtime
permissions/scheduling??  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
