Thanks for your replies. I figured it out. I knew I would feel
foolish... My card is the older card and has no on-board mixing and no
cool utility. I have a hammerfall 96/52
card with AEB8-I and AEB8-O expansion boards for DACs.
Here was the problem

/proc/asound/card0/rme9652

Needs to be Internal input source for my internal dacs. DOH!
it now reads:
ADAT1 Input source: Internal
IEC958 input: Internal
You might think I would notice that I need an *internal* source for an
*internal* dac.
I was able to change the input source using alsamixer.
