We use AVPlayer, AVPlayerLayer and our own custom controls for video playback and are trying to match what AVPlayerViewController offers out of the box.
One option that AVPlayerViewController has that we can't figure out how to match is "Prefer AC3 Passthrough".
Is there a way to implement this behavior outside of AVPlayerViewController? It seems like it could be a configuration on AVAudioSession but I'm not seeing anything that points to that in the documentation.
Thanks!
