ADAU1761 Configuration steps

Hi,

          I have the audio working when configured using SigmaStudio. But when the register settings are written from uC, all I get is continuous ticking noise. I am using the same register settings as done by SigmaStudio and set them in the same order as the tool. The registers settings were verified by reading back the registers.

 

I can reproduce the problem using SigmaStudio with the following  steps.

"Link Compile Download" -- > "DSP Read All" (Audio working till here)  - -> Reset board --> Write back the register using "DSP Write All" 

 

Any idea how to debug it? Or any pointers on what I might be doing wrong?  Attached is the register settings in the order they are written.
