Adv7611 audio setup

Hi,

 

We are using the below configuration for adv7611 video & audio. We are sending the PCM audio to the adv7611 chip but not getting any audio from the adv7611 chip.

 

We have probed the MCLK LRCLK & SCLK and it's look fine (Please refer the attachment)

 

Checked the register status & getting the below status.

AUDIO_SAMPLE_PCKT_DET = 0

AUDIO_MODE_CHNG_RAW  = 1

 

Could you please give any suggestion on this?.

 

if we are setting the MUX_SPDIF_TO_I2S_ENABLE as 1 means we are getting some noise on the audio DAC.
