> Information from channel is taken to derive the channel's sampling rate, suiting SLINxx format and frame->datalen.

> Limitations:
> * Required information is taken from channel during initialization as audiohook does not provide this information then. Audiohook.internal_sampl_rate(...) is set later, but no callback is available to inform app_jack.
> 
> * Frame.datalen is computed using "rate / 50" assuming a ptime of 20ms.
> There is no internal API available to determine datalen for a SLINxx.
> 
> * Ringbuffer size is now dynamic depending frame.datalen (see above) and the number of frames, which are in RINGBUFFER_FRAME_CAPACITY, that need to fit.
