I like “High Horse” from that album. Here are a few things to consider for Apple Music. It looks like you need to go into the phone settings and turn on atmos in the Music app settings. It may be set to “Auto.” You can select “Always On” and the the Dolby Atmos logo will be displayed on any track that contains Dolby Atmos while playing it.
Ok, so the bad news. Airplay 2 cannot send atmos to the receiver and you will get a two channel track sent over in 16/44.1. Jury is still out wether or not Airplay 2 does the 24/48 conversion like an HDMI connection does on Macs and the Apple TV 4K. Whatever it is, it sounds very good but is not atmos.
At the moment, getting atmos to the receiver from Apple Music can only be done using an Apple TV via HDMI. Though, this means atmos tracks, hi-res tracks and CD quality lossless tracks will all get the 24/48 treatment. The Yamaha will then be able to playback and display the atmos information as it recognizes the atmos metadata, provided atmos is enabled in the Apple TV.
“But, all of my speakers are working. How can it not be atmos?” If all speakers are on, Dolby Surround or DTS Neural:X may be active. It could also be any number of the sound modes in the Yamaha. If you like it that way, try it in Dolby Surround with Center Spread on. For the actual atmos experience, you’ll need the Apple TV for Apple Music atmos tracks.
