Thanks for the pointer - trying to deduce the format from the old jack1 patches
(is there an official documentation?).

So FreeBSD AFMT_S24... is incompatible with OSSv4 AFMT_S24..., but comparable
to AFMT_S24_PACKED as defined here:
http://manuals.opensound.com/developer/formats.html
Is that correct? Which combinations of S24, U24, LE, BE are actually used?
Our jack1 only supports S24_LE, which is also what i have in hardware.

jack2 does not have a 3-byte int conversion from the internal float format, so
we have to provide one for input and output. I'll get to that tomorrow.
