Atmos itself isn't channel based.Īpple use DD+ in association with their streaming service and the Atmos metadata would be included within the DD+ audio package. Atmos is fascilitated by metadata include with 7.1 DD+ or TrueHD packaged audio. You'd not need to output anything more than 7.1. I wondered if buying a dedicated USB-C to HDMI adapter - and then using a separate HDMI cable from the adapter to the amp would make a difference (rather than a single cable with USBC on one end and HDMI on the other - just in case the cable is able to send the 4k picture but not the atmos audio with it? Or are the 2 are encoded together?) And there's no indication on the MacBook as to what audio is being transmitted. There doesn't seem to be any specific audio settings. The only adjustable settings on the MacBook Pro whilst playing the movie is under 'preferences' and then 'playback/streaming quality:best available'. No sign of 5.1 sound, let alone atmos! I can of course get the amp to convert the 2.1 to DTX:NeuralX 5.1.2 but this is only simulating a surround effect and is not the core atmos track. But the audio is only registering on the amp as PCM 2.1.

So I get the full 4k picture passing through the amp to the screen at 60hz. I have a Dolby Atmos amp (Yamaha RXV 685) so I hooked up the MacBook to the amp via a 2 metre 4k/60hz USB-C to HMDI cable (because MacBooks now only have USBC/Thunderbolt 3 connections).

So I thought Id try out the new Greyhound film with Tom Hanks, which is streamed in 4k with dolby Atmos.
