I know that Airplay re-samples everything to 16-bit, 44.1 kHz and transcodes to ALAC for transmission. And, I also know that the 2d/3d-gen Apple TVs have a fixed output of 16-bit, 48kHz.
However, when using HomeShare (i.e. pull) versus Airplay to play audio from an iTunes-hosting Mac to an Apple TV 3, what happens to 16-bit, 48kHz Apple Lossless tracks?
I am hoping that HomeShare playback doesn't re-sample these tracks, but who knows? I ask because I have a large collection of hi-res tracks that I've re-sampled to 16/48 (from 24/96, 24/192), using iZotope64, and wonder how these will playback via ATV 3.
