I have been struggling with reading the 4 ADC inputs from the ADAU1777 into the ADSP-571 for a couple of weeks now. The issue seems to be that I cannot pack the 4 ADC channels into a single serial stream. I continuously have to change ASRC 0 source select to switch between ADC0-3, depending on which AIN is being used, to get playback. I have attached my Sigma Studio project, does anything else need to be done from the Schematic window? I am pretty confident on the register setup in the Hardware Configuration.
The ADAU1777 is operating as MASTER to the ADSP-571, I have also attached the ADSP software responsible for receiving/transmitting, as well as the SRU settings.
Can someone please assist us on this issue?

Please let us know following details,
1. Is the DSP processor name you mentioned correct?
2. Are you getting proper BCLK and FS clock at DAI pin's connected to DSP from ADAU-1777?
