[RDD] Still don't know JACK

Well, it looks like my current problem is not JACK at all but liquidsoap.
liquidsoap doesn't appear to like Debian 8, but darkice does.
"strange errors" and segmentation faults don't happen with darkice, and
I'm able to get Rivendell to feed darkice via JACK, and to generate a
stream with programming on it.
Next, I need to see what I can do for audio processing.
