IT LIVES!!!!
Well as well as it can live considering the charge pump is only putting out -1V and the -2.5V reg is then regulating that to -0.25V. As a result to the output op-amps rails are 2.5V and -0.25V.
Setting Foobar's volume way low, I can listen on my capactively coupled cmoy and it sounds pretty decent. No further comments on the sound until I can get the output rails straightened out and listen to it in my normal setup.
Things learned in debugging so far:
1. Reversing Data+ and Data- from the USB won't get you anywhere
2. If you want I2S out of the DAC, you need to tell it that.
