I think i have an EDID problem using the which causes my ADV7623 pcb to not pass through signal.


I am using the recommended configuration script

":1-3 Port A Audio Pass Through Mode for 192KHz multi-channel PCM:"


I have made a drawing of the setup which i have attached.

Short story: I have to connect a HDMI signal generator between my source and my pcb inorder to get a picture on my monitor. This leads me in direction of something failing with the EDID handshake between source and my PCB.


(It's the same story when i try my code on evaluation board, configuring its ADV7623 through i2c - I need to have the HDMI signal generator between eval board and PC source)
