FLAC files ripped from Blue-ray using Makemkv and DVD Audio Extractor
Thanks @Michael_Harris. I had no idea Atmos could be ripped to FLAC. This maintains all the object based Atmos info including the height channels? And the when played through Roon, it just gets mixed down to 7.1?
I am not sure if it maintains the object nature, but I donât know. It is more likely that it converts it to a 7.1 mix which is how they appear in Roon.
Still sound amazing played back through HDMI
I also rip them to move format and keep them in Plex

Atmos is object based and all object info will be removed. The channels will remain for the 7.1 surround and depending on your conversion software will maintain the 24 bit.
Still sounds very good, but there are no height channel information.

You CAN, though, rip to MKV files and retain the Atmos encoding, which plays well through various video players, including Infuze.
Even if they donât expand to support MKV files, I would love to see Roon at least support bit-perfect streaming of Atmos content from (say) Tidal, which should be decoded properly on Atmos-enabled endpoints (e.g., AVRs, etc.).

Best way to do it.
This rip will convert them to a MKV file and will keep everything lossless.

Yes and I also hope that one day Room support mkv files, possibly even ISO files, but that might be too much of a stretch

Support for more than 8 channels would help too. I convert atmos from blu-ray to 7.1.4 wav with the Dolby Renderer + MMH but have to use audirvana or VOX to play the files.
Thank you for clarifying @MikeD!

Well, I didnât read EVERY comment, but I donât see this feature being added unless thereâs a lot more votes.
Simply because Roon would have to make a lot of development and work with Tidal, licensing, etc, only to become a proxy between Tidal and your Atmos device. There is zero possibility for Roon to process, equalize, etc this format in any way. If it does, it would be with the âfall backâ format, which would be almost the same as the normal Tidal stereo track.
I would like to use the âresync delayâ feature, because now I have handshake pauses with Atmos, that are really annoying.
But as a library manager, Iâm okay with using Tidal, since there arenât many good Atmos albums for me. Iâm looking for real good use of the format, not only a glorified 3.1 channel sound experience (e.g. singer on center channel, bass to subwoofer).
âRiders of the stormâ, is a very good demo of what can be achieved with Atmos.
In my opinion the future will be Atmos. Keep voting here to show support, and Iâm fairly sure Roon already got this in their roadmap. MUSE actually can be skipped for Atmos, it will make everything much easier (at least that will be a good first step).
Support via Nucleus/ROCK HDMI, and for compatible Atmos enabled Roon Ready endpoints via network. If Roon Ready endpoint does not support Atmos - it should work exactly like today (same way that some Roon Ready endpoints support 5.1 and 7.1, while most only support 2 channel stereo).

I have to laugh, I commented on a Roon post on Facebook last week, asking when Atmos would be playable via Tidal. I got a reply from Roon telling me to add a feature request 
Ummm this one has been on here since January 2020!!!
Funny stuffâŚ

I donât think the people from Roon responding on Facebook got the full overview of all features and plans.
As next i will now download Mac OS Sequoia Beta Public 2 where, according to Apple, Dolby Atmos can be output via bitstream and, with a new HDMI passthrough setting, the decoding of the audio signal can be left to an AV receiver, for example, if the respective app is also compatible.
Currently, the procedure apparently only works with Apple TV, Tidal App on Apple TV, Apple Music and QuickTime Player.
Apple has shown the way and now Roon is being challenged again, because there is no longer any reason to ignore 3D audio and not be able to take it from the streaming services and forward it 1:1 to the amplifier via HDMI passthrough, as this is now possible with the new MAC OS 18 directly from the Mac to compatible devices with newer HDMI connections.
The currently supported apps only include Appleâs own apps.
There is currently no central system setting; instead, the setting must be made in each app itself.
In addition to Dolby Atmos, Apple also supports other 3D audio formats via HDMI passthrough.
Gone are the days when you had to think about intermediate DACs on the headphone connection and overpriced additional streaming servers for 3D and Hi-Ress.
I tried it out today on the Mac Mini in the OS 18 beta and set âPrefer pass-throughâ and âDolby Atmos automaticallyâ.
It works absolutely brilliantly. My Arcam AVR21, which is now connected directly to the Mac Mini via HDMI, automatically switches quickly and seamlessly between Dolby Atmos and 2 channel Hi-Ress Lossles at 24 bit / 192 kHz depending on the audio format of the track in Apple Music. Iâm curious to see what Roon and Tidal will do now. My decision to stay with Roon and Tidal or to dive completely back into the Apple universe will depend on whether they implement 3D audio for Mac OS or not. Apple is going full throttle and has also announced that the new Apple Airplay can stream multi-channel and higher resolutions and their own music catalog is fantastic for this, especially there is no lack of well-produced Dolby Atmos content and alternative Hi-Ress. Compared to stereo and even the fantastic multi-channel stereo of the Arcam via Roon, this is a leap in quality. Using the Arcam AVR and calibrated with Dirac via my 6x KEF Q150 satellites, 1x KEF Q250c center and 2x KEF Cube 10b subs, I can enjoy excellent music in 3D or 7-channel multi-stereo, which in terms of spatial sound and stage imaging surpasses most of the impressive hi-fi stereo systems and speakers in their impressive rooms, no matter how sophisticated they are.
