How to configure SPORTS for ADC/DSP/DAC

I want to have 3 ADAU1977 ADC's using TDM16 mode, one as port master the other two slaves. The port master will supply LRCLK to slaves and the DSP, the slaves will use LRCLK for PLL source. I then want the DSP to process the data and route the final audio data out to an ADAU1966 DAC that will also be a slave and use LRCLK for it's PLL source. I have ADC/DAC initialitation values but I cannot successfully pass audio. I am trying to eliminate multiple oscillators in the current design where each IC uses MCLK for PLL source.
