Hi,
I have been searching all over for a way to do this on macOS: playing different stereo files on different pairs of audio outputs of the same hardware device. I am currently using AVAudioEngine with two AVAudioPlayerNodes and I can mix them and change the mapping of the entire mix through the use of AudioUnitSetProperty on the engine output, but I cannot have multiple AVAudioPlayerNodes play on different outputs.
Obviously, being on macOS I cannot use AVAudioSession...
Thank you if anyone has any idea on how to achieve this !
