Some of my DTS movies show up as DTS, other DTS films show up DD

I have a decent Windows 10 Ryzen 5 CPU with a 200 Mbps network connection. Many of my DTS films show up on my Roku with DTS. Others, like Lord Of The Rings, show up as Dolby Digital. If I switch to Force direct play, I get DTS, but I don’t know why I need to do that. I’m using Version 1.18.9.2578 and I can’t find any handles for audio on the PMS. Do I need to change something in the Roku Plex client?

EDIT - I found a screen on the Dashboard that said LOTR was DTS-ES 6.1 and was trancoding to EAC3. Couldn’t it just decode to standard DTS?

Nothing? Watching Aliens tonight in AC3 instead of DTS. Just can’t find any audio handles…

In the plex channel, there is an audio setting to enable DTS Core passthrough for DTS HD variants. Try enabling that setting and let us know.

By Plex channel, do you mean the Roku app? I will look again for handles there.

One thing worth noting - some DTS (core, not HD or MA) movies play DTS. It’s the higher bandwidth ones that get the audio shaft. I don’t mind transcoding the video, just wish I could skip the audio transcoding. I can always switch to direct play, but would prefer not to have to.

Yeah. The settings in the Roku Plex app. I always tend to call it “channel” since that’s what Roku decided to call apps :slight_smile:

Roku had one handle, Automatic or not. Uncertain what was automated or not!

Does anyone else have their DTS transcoded on higher bitrate films? Is there no way to stop just the audio from transcoding? Roku does not appear to have any audio settings.

Sorry for the confusion. I was referring to the settings located inside the Plex channel on the Roku, not the Roku platform settings. You should be able to find the Plex for Roku settings following the steps below.

  1. Open the Plex channel
  2. Click your username, located in the top section of the sidebar
  3. Settings -> Audio -> Allow DTS-HD
