ADAU1701 PROBLEMS WITH AUX ADC

I have configured the input for an AUX ADC as the attached image,

 

I do not understand why the audio played is very noisy,  to have a discrete playback, it is necessary to set the control adc in SigmaStudio with No Ysteresis.


This is a problem, the setup in SigmaStudio for the mode of use of the ADC is the same for all.

 

I need to have ADC0 and ADC1 with 4 bit hysteresis setup, but with this setup the audio sent to AUX ADC also filtering is played horribly.

 

I certainly make some mistakes, but which one?

 

Thanks
