Configuring ADAU1761 to work with ADMP421?
In SigmaStudio, there is a Hardware Configuration option to enable Digital Mic. After that is enabled, does the mic signal from the ADMP421 eval card simply come in to a regular input block on channel 0? CN-0078 doesn't say anything about configuring the design in SigmaStudio.

Yes, the digital microphone inputs use channels 0 and 1 of the ADAU1761's input block in SigmaStudio. When the digital microphone input paths are enabled, they replace the ADC inputs (one one or the other can be used at once).
