Assuming you're measuring a 'clean' channel, the ?? most probably
mean a discontinuity in the signal seen by jack_delay. In the
sense that part of signal was 'jumped over' - a short gap that
preserves the timing would not have any effect. This happens
when Jack skips one or more cycles, and this in turn can be
the result of an xrun (also of other things, but not in this
case). Is your Jack running RT ?
