Hi!

I am developing the Matrix product using ADV7623.

<system description>

INGRESS(ADV7623) - ADN4604 - EGRESS(ADV7623)

 

I have a qustion about "External Audio In through the INGRESS".

I already implemented the AUDIO IN at EGRESS but couldn't implement this at INGRESS.

 

I used AUDIO PASS THROUGH but there is no response.

I know that INGRESS is used for Receiver only.

 

<question>

1. Could you advise how to implement AUDIO IN at INGRESS?

2. I can see the selector between origianl HDMI data and the controled HDMI data in block diagram.

    Please see below red circule. What is this? Let me know the register.

Thanks.
