Orl - I'm not sure I understand your problem. Are you not getting DTS or is your video not streaming? With regards to the first, do y have passthrough enabled? If yes, DO NOT active 8 channel sound
Sorry for my english.
In Kodi 17.1 I have no DTSoutput, all the video are in dolby digital. I think the problem is Kodi, because when I play a video with the Android player the DTS is OK.
Yes passthrough is enabled and activate two channel in Kodi. In the "player settings" of Kodi I must activate "Sync playback to display" to have sound otherwise i cannot hear sound.
