I have questions on the audio data paths in the part.
Do the analog audio signals route to the audio formatter?
... or what are all of the places internal to the IC that the analog audio signals get routed, in digital format?
What I am trying to accomplish is to route all of the audio, analog and digital to an analog stereo port - two analog inputs and three HDMI inputs.
I think the way to do this is to use the analog output from the mux and feed the Formatter output back into the I2S input at the bottom right of the block diagram. I am not sure if any HDMI audio can get routed to one particular formatter output. The audio amp that I am using has a 2:1 mux for its each L and R input.
See attached schematic page - it shows looping the digital audio back in to get converted to analog. Will this work to route the HDMI audio to the analog output?
