Is it broken somehow in plex?
My AVR can handle DTS and after tinkering with options I was able to plex play DTS files and I can hear audio and AVR shows DTS logo but the video is skipping fast forward.
With SPMC and Kodi DTS those files work fine, after I found in the settings the options to enable passthrough for different audio formats. I wonder why those were hidden so deep anyways...
Anyway, I rather use Plex than Kodi tbh. But atm I must watch movies with DTS with Kodi :(
Mi box does not function how you want it to. This has been broken on mine since I got it in December. Try another device.
This problem has been well documented. Unfortunately, the only "fix" for now is to use the Plex plug-in for Kodi. Not as aesthetically pleasing as the official app, but works fine.
I too suffer from DTS woes. AVR see's the signal, videos plays in sync for about 10 seconds and then kicks into fast forward mode
I just replaced my AVR that was from 1999 that only had analog inputs & 1 Digital coax and 1 Optical input. thinking the MiBox at time of purchase would pass the Dolby/DTS to the AVR via optical..... but nope that didn't work. Still stuck with it. It worked for this long, but I fell into a good deal at Best Buy for once. It's a entry level Onkyo (TX-SR353) I don't really need anything fancy.
I did notice that Plex doesn't like to pass ACC 5.1 but AC3 5.1 (could be a setting if anyone wants to correct me please do) just transcodes to stereo.
Just wanted to share.
comments are welcome PM with questions.
Why don't Plex simply activate the "external player" function for android TV? Like it is in the regular android app. Then we could just use a player that isn't broken...
