There’s still another weird issue though. On the FireTV Cube (3rd), KODI is able to passthrough TrueHD, DTS-HD MA/DTS:X and AC3, but fails to passthrough E-AC3. When playing a movie which has E-AC3 (99% of the WEB-DL’s) my AVR doesn’t detect anything and there’s no sound. A work-a-round is to disable E-AC3 passthrough in KODI’s settings so it will be converted to multichannel PCM, but this shouldn’t be necessary.

Mmm … I’ve got quite a few of those (TV shows mostly), the Atmos from those will be dropped, I’ll check on that.
Could you elaborate on this?
Which version did you end up using? Tried the ones in boolean’s link but Plex won’t open after installing it as an addon.
I find installing Plex as an add-on cumbersome to use.
I only use PlexKodiConnect which does seem to work.
I installed the Nexus apk with firetv in the name.

PlexKodiConnect is indeed the way to go (with KODI)!

The person I was replying to didn’t know the difference between an apple and a banana 
He/she thought that lossless DTS-HD MA is the same as lossy DTS.
On Kodi 19.5 with the Plex version 0.35 add on, I also played a DTS-HD MA 7.1 file and my soundbar advised it was playing DTS:X.
Was it just playing in High Resolution Audio + X - Lossy with Spatial Audio that Achilles advised.
Edit: trying Composite add on with Kodi, playing TrueHD files are showing as Dolby Atmos on my soundbar (Samsung Q930).

Hello, In Kodi 19.5, with the Plex add-on, I can play DTS:X, DTS-HD, DTS, ATMOS and Dolby Digital (Converted automatically to Dolby Surround) through my Denon AVR-X-1300W receiver and the appropriate decoder description is seen in the receiver panel.
The audio settings are:
- Channel - 7.1
- Best match
- Pass through - Kodi IEC,
- and all the different formats like DTS, DTS-HD, Dolby Digital, Dolby TRUEHD etc, checked.
However, in PLEX app that I have in FireTV cube, there are no such options and hence the player defaults to playing only DTS Core (DTS-5.1) from the DTS:X and DTS-HD soundtracks. This needs to be appropriately corrected by PLEX developers. The Firetv Cube is capable (Seen fro Kodi 19.5), just that the appropriate s/w upgrade from Plex has not yet come.
My plex is updated to the latest version. Here is a snapshot of DTS:X playing through Kodi 19.5 with official Plex add-on (ver 3.5).
Please help this in core Plex player for FireTv Cube.
thanks

This happens so often, it’s very distracting.
The fact that Kodi is able to pass through audio by some means that doesn’t stick to the Andriod development requirements has no bearing on whether Plex can do this.
This has been pointed out in this very thread already and it appears from information already posted by others in this thread the audio that is supported for pass-through on the cube does not to include DTS-HD Master Audio and DTS:X for example.
My claim about the audio codecs supported for pass-through on the cube might not be accurate but that is the way it appears from the information in this thread.
But I am getting DTS, DTS-hd MA and DTS:X signal lit up in my receiver, so the Kodi is somehow making the native signal passthrough to the receiver.
My point is that the FireTV Cube 3rd gen’s capability is not in doubt then - it is just the need of the PLEX software part of it to catch-up then!
Kodi is using its own VideoPlayer in which the team (and co-developers/community) has put much effort in throughout the years. I honestly don’t think the Plex team has the resources (read: engineers with the required skills and/or capacity) to accomplish that. Instead they lean on Exoplayer, which is an extensible media player for Android (by Google). It’s far better than Android’s MediaPlayer API, but nothing compared to Kodi’s solution.
As @boolean described it’s a huge development effort to not use the built in player.
I’m pretty sure all media servers, Plex, Emby and Jellfin for example, all use the built in player primarily, some of them allow defining an external player which often has it’s own set of problems.
What your hoping to be done isn’t trivial by any means, it’s a multi-year project.
Even if there was an appropriate player that could be used instead of ExoPlayer then there are always significant challenges with that too, we’ve seen that when trying to use mpc as a player instead, for example …
Thank you. Now I am able to see the intricacies of the effort involved.
BTW, In Kodi, I am able to play the “hi-end / enthusiast” formats like Atmos,DTS:X,DTS:HD, but Dolby Digital and Dolby DIgital+ (w or w/o Atmos) is faltering and sometimes there is no sound at all, comes out as iffy. I have checked out the capabilities of the receiver in Kodi system setting, however there is no improvement.
There is one option which I have kept unchecked in Kodi system settings, which AFAIK was something like “Transcode Dolby Digital / Digital+”. Apart from that, all others are checked-in.
Anyone have the same problem, as if so, any solutions?
TIA and regards
I don’t have the same problem but I do have an odd problem.
All the encoded movies I have work fine, DTS-HD MA and X, TrueHD and TrueHD Atmos all work fine.
But TV Shows with DD+ Atmos, DD+, DD and DTS all have a 1 to 2 second delay on audio. It’s really odd … the Plex client plays them without problem.
Turning off audio passthrough resolves the problem.
What’s the state of TrueHD and DTS HD MA passthrough on the Cube, still broken?
Was looking at getting one for this feature

Anyone ?
@sixones should know
We spoke to Amazon, DTS-HD / DTS:X only passes through the DTS Core, so whilst its supported on the new device it cant pass all the channels through for the full effect.
We are still looking into the stutter that happens with DTS-HD playback, this appears to be a bug in the OS rather than in Plex. We’ve been able to reproduce the stutter without any framerate, refresh rate or resolution switching and have informed Amazon about the problem. We’ve yet to hear back unfortunately.

That’s a pity, thanks for the info though

@sixones Hope Amazon is increasing their engagement into this. What about truehd support for Amazon Fire TV stick max?
