I think a better solution might be to buffer up enough samples so that
jackd can provide a constant number of frames.

many USB audio interfaces work in a fundamentally
different way than
other audio interfaces. rather than sending an "interrupt" to the host
after processing 2^N frames, they send an interrupt every N
msecs.
And JACK doesn't support this because it needs a constant size
(frames) period. IMHO the audio interface should dictate the period
size and it need not be constant.
Perhaps you would reconsider having JACK use constant (frames)
callbacks?
