You are most welcome!

What I found is that stereo on my laptop works just fine, but in studio with
18ch, I have all kinds of glitches. In my experience, that usually means some
buffers are not aligned or appropriate. The change of channels (and for you,
word length) influencing glitches kinda points to these portions of code:

https://github.com/mekanix/jack2/blob/master/solaris/oss/JackOSSAdapter.cpp#L298-L470
https://github.com/mekanix/jack2/blob/master/solaris/oss/JackOSSDriver.cpp#L232-L395

That's as much narrowing as I could possibly do given today's free time. I will
report progress as I make it, but I would be really glad if somebody more
knowledgable would look at those 4 functions and their ioctl calls.
