How to make MiBox Passthrough Master Audio DTS HD Dolby TrueHD

I purchased the MiBox 16 AB (also called as Mibox 3 not the Mibox S as for most part they were the same and MiBox 3 costs lesser). I was playing around with the settings for a couple of days but was still unable to figure out how to make the MiBox passthrough Master Audio to my Pioneer receiver. There is no proper documantation from MI though the Box claims to play DTS and Dolby audio. After changing and testing lots of Android players of various versions including VLC, Kodi, NPlayer, MXPlayer, etc and fiddling with the MIBox Audio settings, I finally figured out a player and audio setting combination that successfully passes through the Dolby TrueHD and DTS-HD Master Audio to my Pioneer.

First setting to adjust is to do with the Android TV Audio Settings. Under the Sound Setting s in the MiBox, set dynamic range control to LINE. LINE would passthrough whereas selection of RF option will downmix to stereo. Set Sound output to Auto, anything else will simply not pass through the master audio. Set DTS sounds to 20 or 30 percent, though I did not find much difference in setting it to 80 percent either.

The next thing to do is to fire up Kodi player. The version I had is called Leia v18.0. Navigate to the Audio Settings and choose the “Number of channels” as 7.1 or 5.1 dependent on your configuration. Choose “Output Configuration” as “Optimized”. Anything else will simply not passthrough. Scroll down further and under Audio Passthrough, turn on Audio Passthrough. Further select all formats your receiver is capable of handling.

That is it. Now turn off the MiBox and restart it. Go ahead and fire up your master audio files and you should be able to see them passed through and hear them from your receiver. I used HDMI to passthrough the audio but I assume it should be the same if an optical cable is used to passthrough surround sound.

  4. does it also passthrough atmos content via kodi?

    1. I do not have an ATMOS capable receiver. So I am unable to test. But I have seen it passthrough Dolby TrueHD though.

  5. Hi, this doesn’t work on a Mi Box S, it seems that Xiaomi has cut those HD formats out of the Box :-/

    1. May I know if you are running Oreo 8.0 or 8.1

  6. Another solution that worked for me (I found it at after a LOT of searching on google and the likes): go to the settings, to the HDMI CEC submenu and enable all 3 subsettings. Not only did passthrough start working again over HDMI, the MiBox also became a lot snappier.

    1. Thanks Alex, would try that and post results.

  7. Hi,
    I am new with kodi. Does this only help playing files with kodi player? I’m looking for a solution how to play Netflix surround via xiaomi box s

    1. Yes. This solution involves using Kodi only to stream Master Audio. Netflix surround sound works by default in MI Box.

  8. Hi, I also don’t have the option to select TrueHD or DTS-HD in Kodi’s passthrough setting. My Amp is the Marantz SR6013, so is very capable of these formats.

    I have the Mi Box S running Android 8.1. Apparently there’s a bug in the Mi Box S firmware for Android 8.1 that is causing this issue. 8.0 was OK…

    1. Would try updating mine to 8.1 and see if it still works.

      1. Did you updste to 8.1 and still see the true hd passthrough option?

        On my side either i don’t see anything (i have a sj9 atmos soind bar)

        1. Unfortunately, my receiver does not show 8.1 as an available update option. Its up-to-date version is still 8.0

  9. why netflix app not show 5.1

    1. Netflix only have DD+ audio for 5.1, and it’s not compatible with Toslink connection. Are you using a HDMI or an optical connection to the receiver.

  10. Thanks for this forum , it helps a lot.

  11. Hi, everyone!

    I just bought the last version of mi box s, but i don’t have any high resolution sound options on kodi.
    With or without passthrough, it only sends stereo sound to my atmos receiver. I set sound on 7.1, nothing works…

    Any idea Pleeeeease!!!

    1. Can you tell me the version of Kodi you are running?
