Question

Now I'm using my USB interfaces iTwo and Studio 192 with Core Audio and, without UC, they work.

Answer 1

Interesting- I wonder if the SL32 boards would also work. I'm going to hook it up and see if anything shows up on the Audio/MIDI utility.

I read that someone was able to make AVB work through terminal. Sounds cool, but maybe a bit of a pain. Not sure if its worth investigating further on my end.
