Hooray!!!
I'm so glad you got it working. I'm also pleased to know that there are others who realize how great a piece of hardware the D8B really is, totally flexible routing, practically no latency when used with Adat lightpipe and the HDR (I measured it at .4 milliseconds). Very commendable your determination to stick with it and the intelligence to follow your gut. Great work.
Have a blessed day,
Mike
