If there are significant dropouts will that be the likely cause of the "??"
Depends on what you mean by 'dropouts' :-)
I'm running jack with realtime capabilities but
not a realtime kernel.
That should be fine. I haven't used a RT-patched kernel for years.
The loop via system:playback -> cable -> system:capture is only
there to give you the real round-trip latency, it doesn't have
any importance for examining this problem. You could just send
the signal from PA-sink directly to jack_delay.
Try to record the signal coming back from the PA-sink, e.g. using
timemachine. I'm pretty sure there will be discontinuities in the
recorded waveform.
