You probably need to play with sound settings of TV. But, AFAIK, you can only pass through formats that your TV supports. So probably not.
One way to test (if the video codec is supported) - try playing the file from the USB drive connected to the TV.
If I'm not mistaken, this TV model does not support TrueHD either. There is passthrough option but only for HDMI inputs: https://us.community.samsung.com/t5/QLED-and-The-Frame-TVs/Sound-passthrough-option-greyed-out-while-using-tv-apps/td-p/2163302
I have found that one of my video files with DTS can be played on TV with sound (DTS is not supported). Is this some kind of error? This file has 2 audio tracks (DD and DTS) and Jellyfin incorrectly displays that DTS is played when actually DD is played.
Another one with DTS-HD can be played but without sound. But the rest of the video files with DTS or DTS-HD crash Jellyfin.
As for the playback of all formats as PCM via eARC, it is either a Samsung software error or an intentional implementation: https://eu.community.samsung.com/t5/tv/no-dolby-digital-when-hdmi-cec-is-on-only-pcm-works-s90c/td-p/9898544
The TV appears to decode all supported audio formats and output them as:
I haven't tested the optical output. Dolby TrueHD (lossless) is not supported.
In the latest version of jellyfin-web
there is an option to set the priority for audio codecs: https://github.com/jellyfin/jellyfin-web/pull/5434
After setting the Opus
codec the audio is still transcoded to AAC
even though the TV supports this codec: https://developer.samsung.com/smarttv/develop/specifications/media-specifications/2023-tv-video-specifications.html
Are any changes needed on the jellyfin-tizen
side to be able to use the Opus
codec?

No. It is checked here. For Tizen, canPlayType
is used (1 + 2), but it may lie.
Iirc, there is report that OPUS doesn't work on some models, presumably in TS (https://github.com/jellyfin/jellyfin-tizen/issues/130#issuecomment-1208110002).

Thanks for the info. I wonder if it would be possible to decode the audio and stream as LPCM.
Hi, I have AV Receiver capable to decode most of the audio codecs connected over eARC HDMI with S90C TV. When I start playing a video with TrueHD audio for short time I have information on AV side that TrueHD audio is played and after a second PCM signal is played. Is it possible to passthrough audio from the app directly?
