Can you share contents or a link?
Which receiver do you use, by the way? Out of curiosity... :)

DTS, DD, Atmos/DD+ were tested with the Android June update.

We need to check what's wrong with the Dolby TrueHD.
Give us a week for investigation.

Amaze (Lossless-ATMOS) Download MKV H.264 1080p Dolby TrueHD 7.1 ATMOS

There are no TrueHD,DTS-HD option in Android, and the receiver displays "DD".

I think so. We have to wait until Kodi team releases a new Android Kodi app.

I have no idea about any new passthrough improvements.
I think we have to check "IEC61937 Firmware" availability in the Android framework first.

Can you make a list of working/non-working audio format with your AV receiver to improve the passtrhough features?

Hardkernel will not likely be adding code to Kodi to fix this issue, this is something you will need to do yourself I'm guessing.

That would be out of the scope of what they do, the N2 is only a supported media device using CoreELEC.

Do you know if the Ugoos made its own home-brew Kodi app? or just using the official Kodi app from Google play store?

    Yes I read that too that Kodi 18.04 added TrueHD audio, but I think one needs PulseAudio 13 for it and this is not out yet, current release is 12.99.3, so it will not take a long time I think

    Here is the Official PulseAudio 13 draft https://www.freedesktop.org/wiki/Softwa ... otes/13.0/

    @AreaScout ,
    Android doesn't use the PulseAudio directly.

      True, I was just posting it without realizing that I am in Android sub forum :oops:

      But I have seen PulseAudio builds for Android, I think when version 13 is out it will be super easy to use TrueHD in combination with Kodi.

      I will try it on Ubuntu with Kodi 18.04 and a PulseAudio build from current master on my XU4 today, maybe it's already in

      Please try it on XU4 Ubuntu and let us know the result.
      Once you build Kodi 18.4 on XU4 Ubuntu, we will check the TrueHD pass-through functionality.

      But, Android 9 on N2 seems to have a very different audio framework and the PulseAudio might not be adoptable at all probably.

      Yes you will have to ask AMLogic upstream to add support back into the Pie Kernel for IEC61937 audio support.

      There might even be Kernel patches available if you ask the right questions to AMLogic.

      IEC61937 is needed for Dolby TrueHD, Atmos, and DTS-HD MA Android Kodi audio support.

      It was there previously in the old AML Android Nougat Kernel, plus it's still found on the 2016 Mi Box that runs Oreo 8.0

      This has nothing to do with Kodi, but everything to do with getting the correct IEC61937 code support in the AML Android Pie Kernel.

      @wrxtasy,
      Thank you for the explanation.
      But our Android Pie could do ATMOS/DD+ passthrough with Kodi at least.
      https://wiki.odroid.com/odroid-n2/os_im ... ew_updates
      So I think there must be an IEC61937 code in the Kernel.
      Could it be wrong? Or partially implemented driver?

        Hello odroid

        As a side note to XU4, I have build Kodi 18.04 already, it's there viewtopic.php?f=98&t=34149, I also have build PulseAudio 12.99.3 over 11.1 from Ubuntu 18.04 and now I have multichannel-output profile :), however I do not have the hardware to test TrueHD, so if you wanna go for a test, don't hesitate and give it a try.

        Code: Select all

                profiles:
                        output:stereo-fallback: Stereo Output (priority 5100, available: unknown)
                        output:mono-fallback: Mono Output (priority 100, available: unknown)
                        output:multichannel-output: Multichannel Output (priority 100, available: unknown)
                        off: Off (priority 0, available: unknown)
        
        But somehow I am unable to enable passthrough I only got one audio format sink when asking for it, maybe that's my TV ... and the documentation says "If Passthrough was not configured with pavucontrol - no Passthrough setting within Kodi will be available." and that's exactly what's happen, the Audio Passthrough menu stays empty in Kodi :( So I can't wait if it works for you or not with newest PulseAudio

        P.S.: I was following this documenation https://kodi.wiki/view/PulseAudio

            @wrxtasy,
            Thank you for the explanation.
            But our Android Pie could do ATMOS/DD+ passthrough with Kodi at least.
            Atmos encapsulated inside DD+ is a lossy codec.

            When we really want the TrueHD variant which will give us lossless (Bluray Rip) Atmos

            So I think there must be an IEC61937 code in the Kernel.
            Could it be wrong? Or partially implemented driver?
            Possibly partially implemented.

            If Ugoos have got Kodi HD audio passtrhu working with Android Pie, there is likely some AML Kernel IEC61937 patches available or bug busting current Pie Kernel required.
