Is it possible to generate uncompressed 5.1 (multichannel PCM) output from an iPhone?
I'm looking at developing a 5.1 system based around the iPhone as source.
I'm working with the SIIG group to develop a USB Class Audio 2.0 compatible 24/192, 5.1 channel soundcard that should attach to the iPhone through the Lightning to USB Camera Kit (MD821ZM/A).
But it's not clear to me what software I can use to playback uncompressed multichannel content. It may be that I end up writing my own software for this, assuming that I can prevent a stereo downmix or other signal path degradation in the iOS apis.
