We use 7612-7511 combination on our custom board and the ADI repeater application with the HAL and drivers replaced with our own.
With Roku 3, we are seeing issues like this ADV7627 HDCP authentication issue
Matt mentions that there is a s/w fix in the SDK. I'm curious to know what that might be since it could apply to us as well.
Our setup is: Roku 3->7612- 7511-> Vizio TV. A soft reboot of our box(so the repeater application restarts without the power lines going down) triggers this problem on endless Aksv updates. Bksvs are ready and ready bit get set too but every few seconds the video flickers.
Any insights might be useful.
