Sounds good so far.

The ADA8000 has two ADAT cables, correct? Have you connected both of
them? Does the ADA8000 have clock rate indicators? Does the clock rate
follow the rate you set in QJackCTL?

A bit. I thought we were supposed to be able to look at this cards
settings using amixer but so far it shows me nothing for the 9636
while it shows me lots for the AP2496. I'll look at that a bit more
but maybe you know how to use amixer or have some better info on this?

Basically I'm thinking we need to see the card's settings...

I have a 9636 (same card) with all 4 ADAT cables going to two I/Os on
my HDSP 9652.

I always watch the 9636 indirectly by using hdspconf on the HDSP 9652
end. It just works and I don't have issues.

Wish I could be of more help.
