I believe your TV does not support Atmos

Thanks for the reply, but then how does it work without subtitles ?

When audio is transcoding and subtitles have been enabled, the video will be forced to transcode.

Here’s a better explanation of how subtitles and video transcoding works with the LG app: Is it normal for a movie to require 295mb/s speed? No wonder is buffering - #3 by FordGuy61

Thanks so much for the reply, do you think I’ll have any alternative to watch ATMOS releases with subtitles ? Can I somehow use plex to pre-convert the audio to something different as a new audio track ?

You can optimize the video file.
