This is going to be my Automated response to all Krypton Audio Passthrough problems to try and stop frustrations boiling over.

The issue is Android device Firmware that needs updating because of Kodi Krypton's implementation of....

Welcome to Android MediaCodec standards - click here

[thrxxx]

Android Firmware that meets the IEC61937 Audio standard used in Kodi Krypton v17 currently includes the Xiaomi Mi Box and the nVIDIA Shield.

Any other Android Kodi boxes not implementing the IEC standard in Firmware will have DTS and HD Audio Passthrough issues with Kodi Krypton. These devices must use Kodi Jarvis or for DTS passthrough - Transcode the Audio to AC3, using the following Kodi Audio settings:

Number of Channels: 2.0
Passthrough: On
AC3: Yes
AC3 Transcoding: Yes
DTS: No

OR if you want full Audio passthrough with Kodi (inc. HD) with an AMLogic S905 device, flash LibreELEC Kodi to a Samsung EVO or Sandisk Class 10 microSDHC card.

sorry for bugging.

how can I know if an android box is compliant with the IEC standard?
is there a raccomended list for kodi?
I loved my experience with a cheap android box and kodi.... it worked just flawless... and kodi 17 is way better in my opinion...

I loved my experience with a cheap android box and kodi.... it worked just flawless... and kodi 17 is way better in my opinion...

IEC61937 - Currently the Xiaomi Mi Box, NVIDIA Shield &
Devices with Rockchip processors like Ugoos(UT3, UT4, UT6) & Nagrace(NT-N8, NT-V8, NT-V6) also support it.
Just avoid any cheap, zero supported, no name devices with flashy advertisements that mean nothing from Amlogic & Rockchip otherwise you can forget about pass-through ever working.

Looks the Xiaomi Mi Box is quite a guess: not every box works the same, some users can't use netflix properly or the passthrough doesn't work [reddit source]... [and I can't find a shop for europe... is the gearbest model the right one? or is the 3s o 3p version that is crap?]

Well... Not interested in a NVIDIA Shield [I have a PS4] I'm guessing which android set top box is worth to buy... maybe the WeTek Hub?

Using Shield TV 2015 + Turtle Beach Audio Advantage Micro 2 USB for toslink out.

Kodi 16: USB optical passthrough DTS and DD 5.1 just fine.
Updated to Kodi 17 yesterday: USB optical passthrough of DTS and DD 5.1 not working anymore. Only 2 channel PCM will work.

SPMC 16.5.5 works fine after selecting RAW, but I stopped using SPMC a while ago because of built-in subtitles not working from library.

I am wondering whether the Kodi team took ShieldTV + USB audio for toslink into account (however pcm 2.0 works, probably has to do with the fact that I cannot choose RAW over IEC and I think Kodi 16 was not using IEC yet?).

Hope this can be fixed, otherwise "stuck" with kodi 16.

You & I are in the same boat. I don't really feel like going back to 16.1 so until/if this gets fixed, I'll probably have to hook my Roku 4 back up & use Plex to watch my Blu ray rips.

Exact same for me, Shield TV -> Turtle beach USB -> toslink. Lost DD & DTS.
I will confirm tonight, but I do believe passthrough was working on RC3/RC4. An easy solution might be to downgrade 17 final to 17 RC4. Atl least we would still be on v17.

[HolgerKuehn]

Hi folks,

I've just noticed something interesting, regarding the capability to passthrough DTS, but at fist the debug log: The provided log was recorded on the latest 17.1 RC, during this playback no DTS-PT worked, only DD-transcoding. As the Nvidia Shield suports DTS and IEC8..., I found this a bit surprising.

I remembered working DTS-PT on RC4 from 30th January, so I tested this one again ... and no working PT.
While reseting the Audio and display settings I noticed the "Sync Playback to Display" option had been enabled. After disabling this option alone, DTS-PT was working again. So I updated again to 17.1RC, DTS-PT still working fine here.

To cross check this I wanted to reenable the "Sync Playback to Display" option in 17.1 RC, but had not been able to do so, as I couldn't find in anymore ...

I'm going to set up a device this weekend and will check that once again ...


Any hints why this option is missing and able to cause this problem?

...the no-name boxes are in, or slowly but surely they all will be, in the mix. Passthrough works fine with latest upcoming (02/17) firmware releases and kodi 17. At least that's what it looks like, I just look at the logs.

Word to the wise: as RK is actively developing its own private decoder - it can and will break from public standards - unexpectedly, with any given update. If you want standards compliant hardware, whether it be for audio or video related functions, Rockchip is a poor choice.

OTisplay.Mode is where RK won't budge, they are intentionally forking old versions of kodi to build against in favor of their dead end RKdecoder which implements their private, non-standards compliant refresh switching, etc.

Sorry for the users that got trapped, but I'm done with RK because of this. Dropping my last release over at freaktab and game over after that.

Just read its description. It clearly states that it will disable pt. How would you sync to a display without altering audio?

Hi fritsch, I see, thanks for pointing out.

Will amlogic s912 supports DTS PT? It comes with new firmware

The version we had - with the FW directly from AMLogic in latest iteration did it nicely. I cannot tell anything about cheap vendors shipping something ...
