New Audio Engine & Spatial Audio - Works for DTS, EAC3, AC3, Errors with TrueHD

Never once had multi-channel show up.
It was disabled several weeks ago but was re-enabled a few days later.

Prior to it being disabled by Plex, with the 8.21 (6217) beta, I had multichannel Spacial Audio audio show up and work great with DTS-HD MA, EAC3, and AC3 audio, but any TrueHD audio only showed up as Stereo.

Out of curiosity, what about now?

Stereo only on iOS, which makes sense as I don’t believe Plex has re-enabled the new Audio Engine on iOS yet, just TvOS.

But are you still getting Spatial multi channel on tvOS now for all audio codecs except True-HD?

Anyways Plex direct mode hopefully next week in Infuse and then I won’t care that much.
I know Plex will get there and can wait til then but only if they ever disable the fake DV nonsense.

Sorry for the delay. I never got Spatial audio multichannel through Plex on tvOS, only on iOS.

I do get Spatial audio multichannel through Infuse on both (and Infuse also passes DD5.1+ Atmos information to my receiver on tvOS)

Ah cool thanks for clarifying.
I hardly ever watching anything on my mobile or iPad beyond anything I synced in advance with Infuse.

I didn’t even realise that the new Audio player was still disabled on mobile devices.

At the end of the day, Plex direct mode in Infuse is touted for beta next week. I will probably just use that and check out progress onnthe Plex clients every month or two instead of being disappointed several times a week.

Are you saying that Infuse figured out a way to do TrueHD bit streaming ? With or without Atmos?

Nope.
If you’re referring to my “Plex direct” comment I mean that going forward Infuse will connect to Plex directly. No need to wait for the info to sync over from Plex.

All the Atmos stuff I really couldn’t care less about.
All my Plex/Infuse audio is exclusively through Apple devices (HomePods/Airpods).

But. Plex gives us
(referring to, but not exclusively to Apple TV, with the new audio player.)

  1. Audio sync Issues.
  2. No Multi Channel Spatial Audio
  3. New Audio player won’t even start playback if the Audio track is True-HD. (possibly exclusive to using HomePods.)
  4. Audio cuts out after a minute or two when using HomePods.
  5. Fake DV forced upon us. (In the last couple of years of this no Plex dev, staff or ninja has ever made a single comment on this since it was announced as a “feature” in a shiny blog post and announcement.
  6. 60FPS playback. * (see below)

If something has one or two issues then I will keep faith/hope. But with all these issues almost exclusively not even acknowledged, then less so.
Infuse has none of these issues.

  • Perhaps when a Plex Ninja is highlighting that Infuse can play 60FPS just fine then it’s time to forget about Plex for a while. With Plex track record on Apple devices I will probably just check back every few months. There’s far too much broken to think that it will be less than several months to fix even half of the issues. Judging from other staff comments they will actually have to buy some devices to replicate half of the stuff that’s broken.

The Infuse UI may be less than stellar but playback just works in all six scenarios above.

Just as an update this seems fixed at least.
Small sample size of a single movie for now but will test more tomorrow.

Still having problems audio cutting out with 4K HDR mkv movies. It’s super annoying. I’ve tried using ethernet and that still doesn’t fix the issue. It seems to only happen on 4K movies with EAC3/DTS tracks only.

Sorry if you have posted it already but what’s your audio setup?
I was gonna post yesterday that audio just dropping out seems fixed too, sadly though it just took far longer to happen. (Around thirty minutes instead of the usual five.)

With my HomePods it definitely doesn’t discriminate against Audio Codecs or Dynamic Range for me. It’s more than happy to cut out on True-HD Atmos, HDR, SDR.

Back to Infuse for a few months me thinks.

I have 2 apple homepod (1st gen) paired in stereo mode, connected to my Apple 4k TV. When watching 4K movies that have HDR and some sort of EAC3 or DTS audio track, the audio constantly goes out. It’s so bad that I can’t even watch the movie. Really sad to see that this problem is still an issue.

Hi first of all. Fantastic news with Spatial Audio. I can only get stereo with my Airpods Max no matter which video I try. In Infuse it works with multichannel.
What can I do to troubleshoot?

Nothing other than hope that someone as Plex eventually buys a pair of AirPods to look into it.
DaveBinnM planned to before he was laid-off.

It’s the same with audio cutting out with Homepods. (Which as far as I’m aware has never been acknowledged)

All you/we can do is continue using Infuse and hope that we come back in 6 months to year and hope something changes. I long since gave up on checking weekly.

Thanks for the answer. But as far as I can see it was announced to be supported in June so as least it is acknowledged to come.

Sorry, what was?

The headline on this topic suggested that Spatial Audio was working with Plex. Maybe I misunderstood and am using Apple TV and maybe it’s not in TVOS

Multichannel spacial audio as working for all audio formats except TrueHD on iOS, however, due to the TrueHD issues, Plex disabled it on their side back in July.

It has never worked on AppleTV

We have not gotten an update since.

@BigWheel any chance of an update on this?

Right ok.
They withdrew the new audio engine within days on iOS. It’s never since returned nor has anything been said about if and when it will.

They kept the new audio engine in tvOS because apparently it’s issues are purely with Spatial Audio and it seems nobody uses Spatial Audio on tvOS.
Plex words
not mine.
It’s as broken now with regards to lack of multi-channel spatial audio as it was when it launched.

There has been no input on the various issues with the new Audio engine on iOS or tvOS apart from one now ex Plex employee.
