[PD] JACK affects UDP rate

[Dan Wilcox]

Peter’s ringbuffer.c works with arbitrary input and output lengths. I think the 256 sizing is required when allocating.

If s_audio_paring.c is generalized already, maybe it can become s_audio_ring.c and used in the other audio backends, as suggested by Christof.
