So all the apps on my TV now provide Dolby Atmos, Sound bar displays dolby atmos when streaming from netflix, Apple TV, Paramountplus and prob others but not Plex, Plex forces the server to transcode it and reduces the qulity quite a lot.
Is there any plans to stop plex becoming irelevent on moden TV’s?
My TV is the Samsung QN900B.
Thanks

There are two forms of Atmos for home theater:
The Plex app should passthrough Dolby Digital Plus Atmos to the soundbar.
TrueHD Atmos will be transcoded by Plex Media Server. No TV, including Samsung, permits TV based apps to pass TrueHD Atmos to audio equipment via HDMI-eARC. It is a TV manufacturer, not Plex, restriction.
Note that all DTS audio formats will also be transcoded by Plex Media Server, as the TV does not support DTS audio either.
If you want TrueHD Atmos and DTS audio to direct play, acquire a Nvidia Shield Pro (not “tube”) and attach it to a HDMI input on the soundbar.
The Samsung TV blocks DTS passthrough from HDMI attached devices (reference: rtings.com). If the Shield is connected to an HDMI input on the TV, TrueHD Atmos will passthrough, but DTS will be transcoded.
Why direct to the sound bar? The TV supports Atmos and connecting the xbox series x to the TV results in TrueHD Atmos pass through although for some reason the xbox sufferes from some strange stutter issue but it does work and stops the server from transcoding it., I did notice no DTS support though which the sound bar (Q990B) does support. Direct to the soundbar has the issue or not supporting 120hz and limits the xbox to 60 if i went direct but i guess is would get DTS support doing that but lose all the HDMI2.1 features. really reluctant to throw even more cash and more devices at the problem when it did seem others had solved the problem but you are saying its not TrueHD on the apps that trigger the sound bar to display Dolby Atmos when streaming, so disk swapping on the xbox is the only way with out throwing a nvidia shield pro at the problem 
which is mega disapointing
Smart tv’s are designed for streaming, not ripped blurays.
Regular bluray players include all the necessary hardware to output to any hdmi tv capabilities.
So it’s not really tv manufacturers responsibility or prerogative to be compatible with something that was never intended to be streamed directly to a tv without a bluray player (ie bluray/4k rips and truehd/dtshdma).
You made no previous mention of an xbox and frame rates for gaming.
Simply letting you know the TV will block DTS passthrough for HDMI attached devices.
Obviously your system, your priorities. Connect things as you see best.
Does any other TV BOX support Lossless audio passtrough via PLEX? Nvidia Shield is too old device and i don’t wanna invest in such old tv box.
For example this device have capable hardware but i don’t know does ca make passtrough via plex…
The three devices known to passthrough dts-HD MA and TrueHD audio are:
The current Nvidia Shield Pro was released in 2019. The Xbox X was released in 2020. I still receive Android TV updates for my 2015 Shield.
For Plex, people seem to prefer the Shield over the Xbox.
The Cube v3 was recently released. Plex must update their client before DTS & TrueHD passthrough will work correctly. They recently released a beta build, but have more work to do before passthrough works correctly.
Plex is streaming, its just getting the app/tv to allow high end streams which it seems is still not there yet seeing is the tv is only allowing DD Atmos and not TrueHD Atmos, if all the big streaming services offered this high end streaming compareable to Bluray 4k and not some heavly comrressed stuff we get currently then maybe things woudl improve.
streaming meaning commercial streaming services. netlfix/amazon/hulu/etc.
none of which offer truehd over streaming.
other than https://www.kaleidescape.com/ (which requires their own specific hardware) it is unlikely that we will ever see any streaming services offer truehd (or bluray bit rate 4k) just based on bandwidth costs alone (to the streaming service, not you).
in any case, it effects everyone, and the best/only solutions remain as already mentioned above
