I've just been setting up Jellyfin on my LG C4 and have come across this post. I think I'm seeing the same thing. The C4 reports "Dolby Vision + Dolby Atmos via soundbar" at the top right, but it's actually only reporting 'Linear PCM' on my Samsung soundbar. Remuxing the source file from mkv to mp4 (Shutter Encoder, MacOS) results in a file that plays Dolby Vision on the LG, and correctly outputs Dolby Atmos to my soundbar.
So, what's going on here and why is the Jellyfin remux different to a manual remux? Is it something we can create an issue for on github? What's different about a local mp4 supporting DV + Atmos vs a Jellyfin remux of the same content from mkv?
It was my (albeit, perhaps novice) understanding that the Jellyfin feature would remux from the mkv container to mp4 on the fly, but that may not be the case.
Edit: Ah, looking at Jellyfin logs, it seems it might be remuxed to HLS-TS, which could be part of the issue. My client currently has "Prefer fMP4-HLS Media Container" unchecked (default). Perhaps setting this would force an mp4 remux...will have to try that and compare results.
