Trying to understand if the Youtube Dolby Atoms demos are truly being sent Dolby Atoms. I have a Vizio Elevate sound bar that rotates the speakers to a up position when playing the Dolby Atoms. This works with Apple TV and Apple Music, but when I play the Youtube Demos it doesn't rotate the speakers. I do get the "Surround sound" through my speakers. The same problem with Prime Videos and Dolby Atoms movies. I don't have Hulu or NetFlix.

It says links to download the Dolby Atmos and Vision files are in the description. You’ll have to download the files and probably use VLC to watch them.
Thanks and YES that is what I had to do. Posted it to reaffirm that YouTube only plays 5.1 and Dolby Vision. Most of the demos don't tell you this and want you to subscribe to their web site (More junk mail) :) :).

Just to correct a small point, YT doesn’t support Dolby Vision, only HDR

I would humbly submit my Surround Speaker Check tvOS app's in-app subscription as an additional resource for Dolby Atmos demo content. I've put thousands of hours into producing content specifically designed to showcase Dolby Atmos spatial audio. If you're looking to see just how good your sound bar's up firing speakers work, there are a couple of jet-fly by tracks which will do just that: An F-18 spatial object test track, and a Spatial Lab episode where I record a squadron of F-35 jets flying overhead. Lots of other types of demo content too (2+ hours worth now), but the jets currently give the most obvious examples for auditioning Atmos height content, imo.

Jeff;
Are you on AVS forum?
I’m “mtbdudex” there also.

I have a dedicated basement HT that’s currently 9.3.6 Atmos, 2 rows with 4 seats each.
Interested in your demo material.

I’m in the middle of HT 3.0 updates, here’s older picture, got all new seats 4 weeks ago.

Nice! - that looks like an awesome room to spend time in with family & friends! And judging by the condition of your old seats, it is indeed well used and enjoyed! (As it should be!) Ooh - is that an actual Star Wars #1 I spy on your back wall? :)

Yes, I am on AVS, though I don't post often. Not sure why... I guess the Apple TV threads seems to be mostly center around troubleshooting Dolby Vision, HDR, etc. I'm primarily focused on audio so I just don't know I would have much to contribute.

You can find my demo material by searching for "Surround Speaker Check" in the tvOS App Store. Aside from the various surround speaker and subwoofer tests, the "Spatial Audio Tests" and the "Spatial Lab" sections in the app are where you'll find an eclectic range of Dolby Atmos demo content, ranging from the F-18 and F-35 jet fly-overs I previously mentioned, to surround sound music experiments and outdoor field recordings captured using either a surround mic array or an ambisonic microphone. (Perhaps my favorite is the Spatial Lab episode; "Dolby Atmos is Going Downhill", where I take a full-size ambisonic mic rig downhill skiing and then produce the results for Dolby Atmos in the home theater!) There are many gigabytes of content spanning over 2 hours, with more always in development.

There's also an iOS version of the app for AirPlay usage, but since I see you you have an Apple TV 4K, you may find the native tvOS app more convenient. Both apps offer three "free forever" Dolby Atmos core 5.1 test tracks, while a subscription unlocks the bulk of the other test tracks and Atmos demo content.

Happy to answer any questions you might have about the app.
