I am using an ADAU1701 as master and have a Wolfson WM8786 ADC in I2S mode (have also set the DSP to that of course). I can see that the ADC is generating bits and the DSP is generating the word clock (96kHz) and the bitclock correctly (32 bits per word clock). The master clock is 24,576MHz. But there is no audio coming out of the DSP? I can generate signals on the internal ADC and also on an external DAC when using the software signal generators in Sigma Studio so I know that most of the circuit is working. I am using input 2 and 3 on the input symbol.
Does anyone have an idea about what to do?
