Normal I can play DTS-HD MA on LG TV if the Movies file have more than 2 audio source ex TRUEHD + DTS-HD MA + AC3 I can play both 3 format of audio above, but if the movies file only has DTS-HD MA the moves i play has no sound.
the emby server i run on raspberry, when i try to open that movies on iphone it’s can play as normally .
The LG TV will play the first supported audio track, so with TrueHD, DTS, AC3, if you select the DTS track it will always play the AC3 track. It doesn't report this change so Emby will report that it is playing DTS, but the TV will actually play the next supported track, AC3 in this case.
And to prove this, play a file with a DTS track and an AC3 audio commentary, or just a DTS track (in which case you will get no audio)
