Right now the code is only for Mac/Windows/Linux, so I'm not worried about other devices. I have watched the Handmade Hero videos for audio, but I really don't want to write all the audio myself if I can help it. Too much other stuff to do, and I know you can get lost in something like that.
I'm currently look at
http://libsound.io/
I seems like a good wrapper for the backend stuff, and probably the kind of thing the HMD community would write. I just hoped there was some resource that I had missed.
