Before selecting any platform, make sure it supports Dolby Atmos from the desired app.
@drummertime has already found that Amazon Music Unlimited Dolby Atmos tracks are not supported on Microsoft’s XBOX consoles and I don’t believe it is supported on Windows. If anybody has experience to the contrary, do chime in.
@TLS Guy is very knowledgeable concerning certain equipment, speaker builds and electrical wiring. He is not a fan of streamers or is up on platforms and supported apps. He has condemned Apple Music in the past because he didn’t understand that Apple Music Dolby Atmos tracks are only supported over HDMI on the Apple TV 4K. That statement is not at all a personal criticism of
@TLS Guy. I simply made it to illustrate the fact that the best hardware cannot do anything with unsupported software. He has had better luck using his LG TV for Dolby Atmos music from another app.
Big companies with big ecosystems will support the ecosystems of other big companies to varying degrees. If somebody has Apple Music and wants Dolby Atmos music playback over HDMI, they need an Apple TV 4K. If somebody wants Amazon Music Unlimited Dolby Atmos playback over HDMI, they need an Amazon Fire TV Cube or Fire TV Stick 4K Max.
The Nvidia Shield is the best device for those using Plex for rips. While it supports Dolby Atmos music playback from Tidal, it does not do so from Amazon Music or Apple Music. But, it is the most capable in many ways and is the coolest looking of all streaming devices. But, for anybody wanting optimal performance from Amazon Prime Video(with HDR10+) and Amazon Music Unlimited(with Dolby Atmos) the Amazon Fire TV Cube cannot be beat.
Anybody with a receiver that supports at least HDMI 2.0 and HDCP2.2 should be connecting their streaming device directly to their receiver, not their new TV. Only next gen gaming consoles and gaming PCs should be connected directly to new TVs supporting HDMI 2.1 gaming features when a receiver does not support HDMI 2.1 features. Using eARC for audio return of connected streamers will only result in more settings requirements regarding proper audio output.
Some streamers bitstream audio signals without much fuss. Some will convert to LPCM and use Dolby MAT for Dolby Atmos output. It can get very confusing concerning signal passthrough and, again, things can really go south when using ARC/eARC to get the signal from the streamer to the receiver.
The Nvidia Shield Pro is getting long in the tooth. If the next iteration keeps the same form factor and remote controller and supports Dolby Atmos from Amazon Music and Apple Music, I’d be all over it for sure.
As a reminder to
@drummertime, your LG TV supports Dolby Atmos tracks from its Tidal app as does your new Nvidia Shield Pro. You might try a free trial of Tidal’s HiFi Plus to check it out on each device.
And, for anybody with any music service, know that rights deals change often and while one album may be currently available in Dolby Atmos on one service, it may not be currently available in Dolby Atmos on another service. 360 Reality Audio is also supported on some services but will only work properly over HDMI on receivers equipped with 360 Reality Audio processing capabilities. Happy listening!
