I have a 2015 Sony Android TV X850C and downloaded the latest version of Plex in the App Store. I configured the player for forced Direct Play. DD 5.1 AC3 works but DTS 5.1 doesn't. If I remove the AC3 track from the mkv file, it doesn't play audio at all. I have tried Audio Passthrough with both Auto and Off configuration.
I read the release notes and I thought DTS passthrough was working in an earlier build. Am I missing something?
mkvinfo on the DTS track
| + A track
| + Track number: 2 (track ID for mkvmerge & mkvextract: 1)

| + Name: Surround 5.1
| + Audio track
| + Sampling frequency: 48000
| + Channels: 6
If you need more information, please feel free to ask. DTS Audio is something I really looked forward to.
I gave up on it. It may work now that both Android TV and Plex had significant updates since I first posted this. Using an external Plex player now and it's working fine for me. For those using ARC, ARC implementations are limited to Dolby Digital at the most. For most using ARC, it's stereo.
