Well, it was my experience of it at least. I had it hooked up to my onkyo receiver, I configred kodi to passthru everything to the receiver audio wise. DD was fine (DD symbol appeared) DTS streams produced no sound.
My acer revo has no issues with DD/DTS/DTS-Master passtru. What setting did you have to enable?
More importantly though I do wish they enabled 24hz playback . For the life of me I can't understand why Amazon/Google/etc don't support it.
Under settings in Kodi and in the audio output settings I just enable "DTS Compatible receiver" option
