HOW TO USE ADC/DAC WITH EVAL-ADAU1701MINIZ

i'm using two eval-adau1701minizs  to make a adc/dac converter.

 

I made some external cables from a eval-kit(for ADC) to connect with the other eval-kit(for ADC).

 

pin16 of adau1701 - LRClk

pin19 - BClk

pin22 - Sdataout

pin32 - Mclk

 

 

And I connected those new cables to the other eval-kit for DAC

 

LRclk from ADC-kit is connected with LR pin of J7 of DAC-kit

BClk from ADC-kit is connected with B pin of J7 of DAC-kit

Sdataout from ADC-kit is connected with DATA pin of J7 of DAC-kit

Mclk from ADC-kit is connected with MCLK pin of J7 of DAC-kit

 

K-1.jpg is the Hardware configuration of DAC

K-2.jpg is the schematic diagram of DAC

K-3.png is the hardware configuration of ADC

After testing with those settings, i expected to linste some music from DAC with speakers which is attached with the evaluation kit for DAC.

But there was no sound

In the schematic diagram of DAC, I checked only pin2,pin3 because i'm using only Sdata0.

 

i'm not sure about how to draw the schematic diagram and set up hardware configuration

i've spent a lot of time to figure out the problem with datasheet, but i'm still confused how to do it.
