ADAU1452 Audio problem

Hello Team,

We are using ADAU1452 evaluation board. 

While testing with evaluation board the whole thing was fine. We got output as per our requirement. And then we made a customized board with similar schematics.

Tested with simple audio program (i.e Playing square signal at output side).  the circuit is not working fine. What may be the problem. Kindly help us to resolve the problem. We are using AD1938 audio codec.
