Any idea how to switch from the original audio source to an external audio source in an HDMI video flux.
The external audio source must be I2S or Spdif.
Which specific part or board are you using?
i start from scratch.
I'm not using any specific parts or board. i'm looking for a solution.
If you use a chip like the ADV7850 you can have the audio source on the video stream pass through. The external souce can just be mux'd in via th APx pins
Normally people will use a HDMI receiver (like an ADV7612) that extracts the audio stream from the video stream and then mux's in either the extracted stream or a new external stream into a transmitter (like a ADV7511)
