I never got DTS files working with my LG OLED. Even after commenting out DTS of the configuration, which should force UMS to transcode DTS to AC3 didn't work. I fumbled around with that to the point that I just went over to converting DTS to AC3 with an ffmpeg command line prompt, that saves me the headache of trying to get it transcoded on the fly.
If anyone has any other suggestion that works, I'll be glad to hear.

AC3 transcode from DTS works for me (C1), check the support thread for my config.

No problem, but why is HEVC being transcoded? For me it streams, and audio is transcoding if needed. My current config is: I just delete all LG* renderers in the renderers dir and add only as per attachment.

I was just testing it. I have a sound bar with DTS support, even then it doesn't work and DTS is not possible. Same situation with direct casting the file (without UMS). DTS possible only on PS5 with BR discs.

When I choose "No Transcoding" the video is fine, but no DTS sound.

When I choose FFMPEG / DTSHD, it transcodes audio + video.

So I guess I have the same problem.

If your TV supports passing though the DTS to your soundbar with ARC then you can edit your conf to add dts or dtshd in the supported formats section so UMS will not transcode it automatically.

Yes, the problem is that LG dropped DTS support altogether since 2020 I think. It won't even allow pass-through.
