Somewhat works here (but not 100%) stable, tested playback and

this part slightly changed: aucat was renamed to sndiod and now is started
using rc.d(8). For instance:

The realtime option -R is commonly used on other operating systems.
However, this option is inconsequential on OpenBSD.

There is currently no MIDI driver in jack that works on OpenBSD.

AFAICS, the sndio backend could be simplified (sndio changed) which
could make jack more stable. I don't have time for it right away, but
put it on my todo list; if someone uses jack a lot and is working on
it let me know. Jack is good software and worths the effort.
