Thanks so much!

What I had working was the BlueGiga board in Analog audio configuration. That still works, so I can continue to use that.

I was really hoping to get this replacement Betz board working again, to get my digital audio working again. The difference in the sound is subtle, but I'm craving having that digital audio working again.

I've got a few other things I'd like to accomplish on this project, too (final PCB design, final enclosure, etc.), but they all depend on the Betz board with the digital audio working and being tested for a while without frying before I try moving forward with them. So it's good that we're taking our time and being careful about making sure this thing works as designed.

Thanks for all your help and advice!
