This is a topic to reopen the task about Atmos on AppleTV.
I can see that many just gave up, and now I really hate that my AppleTV can’t play it because Plex is lazy.
So people, we are going to give et a go again 
Link to the original topic:
Link to a feature request:
Just use Infuse. Plex is a great server, it’s a terrible tvOS app.
That’s for eAC3 anyway. In order for any player or server to transcode TrueHD to eAC3 they need to have a Dolby license. That’s not going to happen.
Plex Media Server can transcode TrueHD to EAC3. Plex does so with some clients. There is no license issue.
What is not possible is transcoding TrueHD Atmos to EAC3 Atmos. That is a technical, not licensing, issue.
See this post at Dolby for additional information: https://professionalsupport.dolby.com/s/question/0D54u00008FGd6YCAT/converting-atmos-to-dd-with-joint-object-coding?language=en_US
If I understand correctly Plex does actually have the requisite license ergo they adhere to the letter of the law unlike other competitors. Tangent I know…
Correct, it does not pass through Atmos per Plex design.
Plex app does not support Atmos of any kind, most DV is kickback to old player, does not support HDR10+.
Plex app is on old pre-ios14 deprecated API that Apple wants people to stop using, therefore no new features.
People gave up, because Plex seemingly abandoned the app.
If you want 3 year old features like atmos and hdr10+. Get Infuse.
I must say it is silly to say “just use infuse” is not good enough. They say that its supported by the server then should the apps allso be supported when the hardware is supported.
So Plex is just not doing their job
Has there been an official word from
plex regarding support for Atmos? Really saddened that it’s not supported.
Well they haven’t even sorted Dolby Vision yet so I wouldn’t get your hopes up for Atmos anytime soon.
Official word is they are using pre-ios14 deprecated API that Apple wants to be rid of 4 years ago.
The iOS app is abandon ware.
Is there any statement from Plex ?
It will be fine, when they will support Atmos in eac3to It is only pass throw to HDMI or not ?

DV works fine if you remix the file with mp4box, witch set the codec to dvh1 instead of hev1. Only rename in Hex Editor don’t work.
There is no known roadmap.
Can we get some info from Plex? 
@DaveBinM you had some info on the last post, so maybe you can inform us about what you are working on?
Sadly @DaveBinM hasn’t been a Plex employee for a good while now.
If you want this, you should subscribe to the Infuse app.
would do if it had multi user support, dont really want my watch progress to get all messed up
I’d help you if I could, but I haven’t been at Plex since June 2023, so telling you what I’m working on these days wouldn’t be much use 
Still happy to provide help and insight where I can though! 
This may or may not interest this discusion.
