Pop noise when reading from ADAU1701

Hi there, how are you?

 

I'd like to know why sometimes (doesn't always happen) the output makes a pop noise when I read data from ADAU1701's register? It happens both using Sigma Studio and using microcontroller... In my application there's a moment that I must read from the DSP the gain value, apply a certain attenuation and then write it back. But this pop noise really can't be there. Is there a fix for that?

 

Thanks!
