Neo T5 Can't Bitstream TrueHD and DTS-HD?

Hi everyone, good if someone's figured out how to bitstream HD Audio through Kodi on the T5.

The audio section within settings doesn't allow hdmi audio. Only PCM and SPDIF options are available. Hence only DD and DTS are bitstreamed on Kodi.

Please help. Thanks...

Check the audio specifications on the back of your T5's retail packaging!!! Unfortunately TrueHD & DTS-HD aren't included which appears to be why they're not available in Kodi's passthrough options.

The default (EDIT - (AUTO)) option in the T5's audio settings is HDMI, PCM obviously has the T5 itself decode all supported audio before sending said audio on to a TV or external audio hardware, & SPDIF sends the audio via an optical cable as expected.

Ergo, no passthrough of the HD audio formats. As you've discovered, if you play a file encoded with HD audio you will still get 5.1 surround of the SD lossy core, i.e. lossy DD/DD+ or DTS. However, Atmos will work if the file is encoded with DD+/e-AC3.

Hope that helps you to cease scratching your head ;).

scratches his head ...i have no HDMI option in audio settings and if spdif is selected without any spdif connection being made audio is still sent by HDMI

Yes, but the point is the OP was "raking his noggin" wondering why the HD audio formats wouldn't passthrough to his external audio hardware & now hopefully understands why not :). (I've also edited my original reply should it save confusion.)

Otherwise, you're still busy "engraving your brain case" because you've experienced an entirely different audio issue to the OP or myself. We at least both have 5.1 surround successfully passing through over HDMI, albeit SD/lossy for HD audio. Not to mention, the audio problems you've experienced with your T5/AVR in this instance are, quite how to put this one? "Seriously funky indeed"!!!???!!!?!!!!! (If I'd been experiencing the problems you described under another thread I wouldn't have been "scoring my cranium", by now it would be terribly bruised & a large dent or crack clearly visible on my desktop in trying to solve it hehe ;)!!!)

Factory reset is your best option! (I can't recall you mentioning you tried one!!???? I'd hate to assume you had & not remind you just in case it works)! If that fails, try @Villa 's method for reaching the T5's recovery menu, clear what you can first & then force the reset from there. See if that perhaps makes a difference? I also made a direct jump from FW 9.3.11 to 9.3.15, whereas you had a brief stopover on 9.3.14. Could also be a factor. Again, a factory reset to start a fresh could help.

Didn't you sideload some additional apps etc. too? Perhaps if you installed something like ES it could be contributing in some weird way, (not unheard of)?? I'd say remove them but we're straight back around to the above lol, yes, bloody reset lol ;):).

As we previously discussed/noted in a separate thread, if I select SPDIF on the T5 I then get no audio at all over HDMI with my AVR. (Which is obviously what one would usually expect without a cable being present, although I have seen other devices where SPDIF could be selected & still work over HDMI.) I also need to specify an optical/analogue connection for any given source in my AVR's settings too if not using the default HDMI. Given that our Sony AVR's are so incredibly similar I know yours has the same settings in that regard. Somehow, one/both of the devices in question is/are somehow still allowing the SPDIF signal through HDMI.

Obviously, manually setting PCM or SPDIF are very specific options that users tend to need for fairly specific reasons/circumstances or external hardware. I'm currently testing SPDIF (with cable lol) on the T5 as well. So far that's held up OK too. The default "auto" option certainly appears to be HDMI from everything I've observed & tested with the T5 so far. Another reason why I've tentatively labelled the auto audio option as being HDMI by default. The other options are very specific & ultimately need to be set manually, (often at both ends of the cable with SPDIF too). "Ordinarily", HDMI (auto) just works out of the gate.

Quite why a fourth selectable HDMI option hasn't been added is anyone's guess unless it's purely to keep things as clean & simple as possible or because auto is in fact HDMI by default lol :)?? The auto setting would still use HDMI by default even if a separate choice was added I suspect.

5.1 SPDIF audio has seemed a little "rawer/harsher" to me using exactly the same files to test for want of a better term when directly compared to 5.1 HDMI, otherwise it functions as expected. (Don't get me wrong, SPDIF sounds absolutely fine, excellent in fact, it's just sources are very slightly louder over SPDIF despite the identical volume level being set on the AVR for both HDMI & SPDIF respectively.). Might simply be a case of fine tuning/tinkering but obviously I wouldn't remain with SPDIF, I'm just testing it should it be of any help :).

Obviously SPDIF is something you could consider unless a reset works. However, the one downside of doing that is if you have managed to get Atmos working correctly with e-AC3/DD+ sources you'd then lose that again using SPDIF (with) an optical cable :(!!!!

These are purely my observations alone, however. It would certainly be a good idea for us to ask John or. Martin for specifics with these settings under the other thread anyway. We'll then know for certain should this be one of those frequently occurring topics :).

Short of me purchasing a DH790 to use as a doorstop, the only other thing I can think of is when I'm done testing again is to try installing the exact same apps as you!! But when all is said & done even that would be pointless until you do a reset to be certain. (After that I could try installing one app at a time & test after each to see if we can recreate the problem again??. Although I have the distinct feeling that if you get rid of this problem you'll probably avoid installing the same apps again unless they're absolutely vital :).)

Keep us updated :).

ouch....my feeling is that this just shows, IMO, that the current T5 firmware is a bit of dogs breakfast, especially when it comes to video/audio output. :eek:

When I get more time i will factory reset and test again :)

LOL :). Not beating around the bush this A.M. are we ;)?? (There ya go MINIX, now you certainly know the score @pusb87 style heh) ;).

I didn't think you'd tried a factory reset. You normally list steps that you've taken/tried when you initially post about a problem :).

Fingers crossed again that there's a fair chance one of the simpler options available to you works out then. (Don't be too harsh in the meantime lol, this could have been another unforeseen side effect of our devices arriving early & exactly how these early updates were implemented with these devices that had to be manually entered into a system by their serial numbers etc. ;))??? (The good thing is, these wee T5's are so simple that the entire system settings & options themselves quite literally takes 5 mins to reconfigure after a full reset & you're immediately good to go again. Obviously reconfiguring Kodi or your other favourite apps takes a little longer especially if restoring a previous backup etc.) Once you've factory reset & installed Kodi again too, initially It'd be best to avoid installing any additional apps until you've tested for this audio problem again. All being well after that, have at it :).

Other than this problem with the HDR being permanently stuck on with our 4K HDR TV's & the obvious side effects of that issue, the visual side otherwise seems OK. Granted, it is a pretty darn serious problem to completely miss given the ever increasing numbers of users that now have HDR capable TV's, & of course a good number of them specifically choosing the T5 because it supports HDR 10+! (I was definitely able to force mine back into SDR mode with FW 9.3.11, however. I just can't remember if I did it using the colour space settings or the Dolby Vision option that still remained in FW x.x.11. It restarted back into HDR mode again though & I got it back into SDR a second time. I just didn't test Kodi in 9.3.11 or its capability (or lack thereof) to correctly auto switch between SDR -> HDR -> SDR & so on. Media playback is otherwise smooth & fluent, no stuttering (regardless of frame rate switching being enabled or disabled etc., or any other problems) Sadly it's currently suffering with this garish over saturation/over vibrance until this HDR lock problem is patched. (It's absolutely typical that after all that time you took to research the best possible TV & waiting for the Black Friday deals too, that you finally upgraded to your shiny new 4K HDR OLED literally days before receiving the T5 too ;). With your old 1080p TV you just wouldn't have been affected by it had you decided to wait for the "January sales" to purchase your TV instead lol ;).

The audio also appears to be fine over HDMI, or SPDIF with the AVR for the purpose intended & supported formats as well :). (You even discovered that Atmos works with the DD+ encoded files too so something in there is doing what it should, it just seems to need a kick in the backside (reset) to get it all back on track again.) Obviously, I too was "scuffing my skull" wondering why the HD audio passthrough options were missing & essentially troubleshooting a problem that just didn't exist before I eventually checked the specs on the box again lol ;).

I also did a reset whilst the box still had 9.3.11 & another soon after the 9.3.15 update too, (in fact it's actually had 3 resets already). I could well have had the same audio issue you're currently experiencing but I reset the device before anything could ever be tested. (I reset from concern about my perceived "update problem", but we now know what caused that one too of course lol ;).)

It certainly needs some tidying up as far as the system menus/options are concerned, no arguments there at all. And yes, PLEASE fix the HDR ASAP guys lol :)!!! After that & the potential resolution of your current audio problem, everything else will hopefully be "groovy" in due course :).

Will wait to hear how your reset goes.

P.S. I've just remembered one last thing I can try to force my TV out of HDR mode via the TV's own settings. Will let you know if it works as soon as I have any info & provide rougb details of what to look for given the different names the manufacturers assign to certain settings :).

agreed, at least in Kodi 18.5. I couldnt get mine to do refresh rate switching.

My testing of a number of multi channel audio formats using Auto Sound out ( HDMI ?) and passthrough enabled in Kodi 18.5 with HDMI cable only connected to AVR.


Multi channel AAC >> AVR shows Linear PCM 2.0
Dolby True HD >> AVR shows Linear PCM 2.0
DTS-HD >> AVR shows DTS
Dolby Digital+ ( with Atmos) >> AVR shows Dolby Atmos - DD+
Dolby Digital >> AVR shows Dolby Audio - Dolby Surround
Dolby Digital+ ( no atmos) >> AVR shows Dolby Audio - Dolby Surround

so in my case just the AAC and Dolby True HD giving "bad" results :confused::)

WOW!! That's a vast improvement over what you were previously experiencing following today's factory reset at least :).

I have tried PCM, spdif and Auto ( the only 3 options)
Multi channel (inc HD) audio in both PCM and Auto all come out (for me) Linear PCM 2.0

but if i set to spdif ( without any spdif connection !) then HD audio will come out as DTS, all the rest as Linear PCM 2-0.

Before your results really were looking incredibly frustrating & the outlook previously quite bleak. Other than TrueHD still being a little stubborn there, that's MUCH closer to what we'd expect to be seeing :). (Are you remembering to use A.F.D. on your AVR in general for the surround encoded movies, (especially HD/Atmos)?)

For AAC (2.0 or multi-chan) you may experience some issues here & there. I get them too, it's not bad but it's not the perfect format. Presumably, in addition to your AVR actually reporting 2.0 PCM for 2.0 AAC actual, the audio is only available on the L/R FRONT speakers as well??? (For AAC, try manually setting Dolby Surround on your AVR instead of A.F.D., it may shift the vocals to the CENTRE channel at least, makes it a little more bearable ;):):).)

With the lossy 5.1 formats you can also experiment between A.F.D. & Dolby Surround (or Neural:X if it's available for you to select.) See which you prefer for the dynamics & general effects for your specific setup too :).

Am glad there's now been some improvement :). I was quite shocked to see your original audio output I must admit!!

actually i think its the same and i had just randomly selected Dolby True HD video files ( which i have mostly) and this time hunted around for Dolby Digital(+) types.

yes i can and have tried all that, also it seems that the low frequencies are sent to the subwoofer. However, when I watch anything I use the U9-H !

Aahhhh, that would certainly explain a lot too, (OOOOOOPS!!) Do you still have the funky little collection of those DTS-HD, TrueHD, Atmos, DD/DD+ & DTS test files as well? If in doubt, they're always a good place to start which I've certainly had to remind myself of too lol!!!. Once you've determined what is or isn't specifically working after that :), branch on out :).

Ditto!! Tried & tested :).

OH, BTW!! I didn't find a "one click" setting for the HDR issue I was hoping for. However, I have found a half reasonable work around for it that didn't actually look too bad at all after a bit of fine tuning. You don't need to be a professional TV installation engineer/calibrator either. It's actually very simple, don't know why I didn't think of it sooner, something you said this AM struck me to look into it :). Explaining it is a bit long winded & it's not going to be tonight either, but I'll PM the abridged version of what I did & post my workaround up under the other thread for the other guys with HDR TV's to give it a go as well if they so wish ;).

It's not true SDR & technically the TV is still in "HDR mode" but it kinda works. Details tomorrow :).
 
Hello,
I also having trouble with Kodi & Plex withe TrueHD passtrough. For some unknown reason, Plex is transcoding the audio to EAC3 and in Kodi I don't have the option to allow passtrough for TrueHD and DTS-HD. Are these not supported by this player?

We've never actually received direct confirmation from MINIX regarding HD audio & the T5 either way but all indications are that the device won't support TrueHD or DTS-HD (HD audio) passthrough. (Consequently, the HD audio passthrough options aren't present in Kodi.)

but they do work when using Coreelec on the T5 !!
