ADAU1761 ADC_SDATA in Slave mode problem

I'm connecting an iMX28 processor to an ADAU1761, using the Linux driver from Analog Devices.

The ARM CPU is outputting the BCLK and LRCLK signal, and I set the CPU as master and the codec as slave.

The DSP configuration is set up with the first two inputs directly routed to DIG0 and DIG1 respectively.


I can play audio fine on the HP output, but I can't get the ADC_SDATA signal to move at all, it just stays low.


How can I debug it? I moved the mixers and set the capture to on, but with no luck.
