ADAU1761 DAC_SDATA remains low, no output

With the following settings, while streaming data from a slave to ADC_SDATA, I cannot seem to do a simple forward of the data through the DSP to DAC_SDATA (Stereo i2s). Here are my settings and a printout of the serial line activity:
Capture.PNGCapture2.PNGCapture3.PNGCapture4.PNGCapture5.PNGCapture7.PNGCapture8.PNG

Channel 2 is pin 26 (ADC_SDATA), Channel 0 is pin 27 (DAC_SDATA). I've tried various combinations of input/output channel selection in the schematic widget. Am I missing something?

 

Edit: After making some registry changes, I see channel 0 at 2.1v steady (I am running everything at 1.8v). Not sure what this means.

 

Thanks,

Jake
