I am developing the Matrix product using ADV7623.
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.
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.
