    -= HELP sound tv box TRUE HD - ATMOS - 7.1 =-

    I am seeking answers to my problem.

    I have nexbox a3 s912 amlogic.

    I can not solve a problem with sound 7.1 android 6.0.1

    My receiver is a Denon AVR-2200.

    Letting go of the movie in 1080p or 4K quality with 7.1 soundtrack, the receiver gets the signal IN as PCM.

    I have read the android can not cope with the sound of 7.1 channel operation.

    What is your opinion on this?

    Sorry for my English as something

    I understand that no one is connecting the receiver to the TV box?


      Cheap S912 devices have lots of problems with pass-through.
      Combine it with a Nexbox and things are even worse since you get no support or fixes for something that was advertised as working in the first place.
      Lots of the Amlogic S905/S912 devices from eg. Wetek or Xiaomi run the latest firmware and patches from Amlogic to have pass-through working correctly.


        after the last update in nexbox a3 began working for DTS 5.1.
        The best solution is probably to wait until you deal with it can handle.

        We need a sound 7.1

        What TV boxes that do not have the problem? besides nvidia shield?


          I found the answer

          I also tested PCM output (stereo downsampling) via Kodi and MX Player/MoviePlayer app using my TV’s speakers, and HDMI pass-through in both using Onkyo TX-NR636 receiver for advanced audio codecs.
          Audio Codec in Video PCM 2.0 Output
          (Kodi 16.1)
          PCM 2.0 Output
          (MoviePlayer or Video Player)
          HDMI Pass-through
          (Kodi 16.1)
          HDMI Pass-through
          (MoviePlayer or Video Player)
          AC3 / Dolby Digital 5.1 Audio OK but video not smooth No audio Dolby D 5.1 detected, but audio starts with noises, video not smooth OK
          E-AC-3 / Dolby Digital+ 5.1 OK No audio Dolby D 5.1, but with 3 audio cuts OK
          Dolby Digital+ 7.1 OK No audio no audio Video plays in slow motion without audio
          TrueHD 5.1 OK No audio no audio TrueHD 5.1
          TrueHD 7.1 OK No audio no audio TrueHD 7.1
          Dolby Atmos 7.1 OK No audio PCM 2.0 Dolby D 5.1 – continuous beep
          DTS HD Master OK No audio DTS 5.1 with 2 audio cuts DTS 5.1
          DTS HD High Resolution OK No audio DTS 5.1 with 1 audio cut DTS 5.1
          DTS:X OK No audio DTS 5.1 DTS 5.1
          No audio with PCM output using apps other than Kodi is expected since the processor is Amlogic S912, and not Amlogic S912-H with the proper Dolby and DTS licenses. HDMI pass-through is still in a sorry state, especially in Kodi. It’s still usable in other apps, as long as you are satisfied with 5.1 audio.


            We did, however, fire up ATMOS TrueHD and for the help Movie Player player system.
            Wine lies on the side of kodiego.




              On Rockchip devices like RK3229, RK3288 all the pass-through audio works good in Kodi and they don't even have licenses.


                any update on atmos? i have Minix h8 plus and Denon AVR 2300 also issues with Atmos sound - looking for a new player to get this sound working, any tested/working suggestion?
