--- Comment #27 from Goran Mekić <meka at tilda.center> ---
I updated the code with (I hope) proper calculation of buffer sizes in
https://github.com/mekanix/jack2/tree/feature/freebsd. It is tested only with
32bit samples, as that's the only thing my card supports. It probably need more
refinement. The base of the idea is to take
http://manuals.opensound.com/developer/SNDCTL_DSP_SETFRAGMENT.html as reference
and replace:

int frag = (max_fragments << 16) | (size_selector)

with:

int frag = (channels << 16) | (size_selector)
