@SubJunk - thanks let me know, I can help with testing if necessary as well on LG C1.

@rhayy - thanks for idea, it's not helping I have:
maximum_bitrate =0
automatic_maximum_bitrate =false

That'd be my expectation too. Unfortunately, it doesn't allow DTS pass-through in any way. It's definitely the case for ARC, and I think also for optical out.

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

Try to cast the file directly (if you have Windows). Do you have the same problem?

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 ...

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.

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

Thanks for the help, the issue was in the subtitles format.

HDR switches to HDR profile in case of Dolby Vision, for HDR10 it uses the SDR picture presets.

I disabled DTS codecs as they are not available since LG CX.

Attached, my renderer file. The only pending issue is fast forward in transcoded ...

Greetings,

Any help gladly appreciated.

1) My test video file is MKV with HEVC+AAC-LC. UMS always transcodes for unknown reason. If I try to force non-transcode, it works. The video has internal subtitles only. The renderer is configured like this:
Supported = f:mkv v:av1|h264|h265|mp4|mpeg2|vp8 ...
