Since Apple TV decodes and then sends LPCM how does Atmos actually work? Right now I have my Apple TV hooked up to an old Onkyo 7.1 receiver. I can see that it is sending 7.1 multichannel PCM for supported music and movies. Since my Onkyo receiver's other 2 channels/speakers are considered "surround back" speakers, is the height channel in an Atmos supported tracks being sent to these speakers?
