Hi!

I am trying to play a bluray movie with Dolby True HD 7.1 using the HiMedia wrapper but it automatically switch to another soundtrack because it can´t play it. DTS 7.1 works fine and also Dolby AC3 5.1. I am using my Bose Bluetooth headphones but have also tried it with my Samsung soundbar connected to my TV with HDMI, same results there. Why does it not work?
I own a Q10 Pro with build-number HMD-2.0.6 2017-10-25.164125.

DTS and Dolby are SPDIF-quality lossy compressed audio formats, Dolby True HD and DTS HD MA are lossless HD Audio formats.  

Do you have an HD Audio compatible AVR to decode these formats?  Is your sound bar compatible with HD Audio - or is it just capable of the lossy SPDIF stuff (a number of sound bars don't support HD Audio) 

If not, and if stereo is OK (for headphone I assume it is?) then if you disable passthrough / bit streaming in Kodi and configure for 2.0 output you can listen to the lossless 5.1/7.1 HD Audio down mixed to 2.0 stereo.
