WE are thinking of using the ADV7623. We would really like to have some SPDIF optical inputs along with our HDMI inputs. From what I read, it’s hard to tell if the SPDIF audio can be routed to the audio processor for output to our DSP. The development board indicates at least one audio input – but I’m just not clear on it. Essentially we would like to switch between SPDIF and HDMI as inputs.
