Adv7625 AP1Out not confiring properly

Hi,

I am porting ADI v1.90.2 code on a custom made board.

The board has Adv7625 as RX & Adv8005 configured as repeater.

Here every thing is working fine as Adv7625 is configured in pass through mode I can see & hear Video/Audio from Adv7625 --> Adv8005 --> TX.

My requirement is to configure Adv7625 to extract audio from RX & pass it to AP1Out, here I am facing an issue when I configure Adv7625 IO Map registers like (08, 0A & 9D) as per data sheet for extracting audio from RX & passing it to AP1Out, the register values get set but I can't see MCLK, SCLK & any audio pulses on AP1Out pins.

 

I also have a Adv7625 standalone code where if I configured the above mentioned I2C registers then everything is working fine, I can see the MCLK, SCLK & audio data at AP1Out pin.

 

Can you please help me on this issue.

 

Thanks & regards,

Saurabh Namjoshi
