Hi, I have a Sony HTIAB, it only supports PCM, Dolby Digital (AC3) and Dolby Digital Plus (EAC3). I sometimes have files with only DTS or TrueHD audio, the problem is Jellyfin FFMPEG only transcodes the audio to AAC which is unsupported and causes VERY low audio volume playback vs if I pre-transcode it to AC3 myself. Of course that's very time consuming, transcoding then remuxing. Is there any way I can tell JF-FFMPEG to transcode to AC3 instead? I dug around all of the Jellyfin installation directory, found a few .xml files with lots of AAC references inside but no clue how to go about it.

Is there a way of modifying the Tizen client to call for AC3 instead of AAC myself?

Thanks

Did you mean "to AC3"?

Those are DLNA profiles - they aren't used by WEBUI.

There is currently no way to set the codec priority using UI. Try this patch for WEBUI - you need to rebuild the app.

@dmitrylyzo Does your patch for WEBUI potentially fix the issue I'm having in #226 ?

Unlikely, my patch (in fact, a test) is only intended to prioritize audio codec when transcoding.

May I ask for a clarification of the problem? Does the Videos with stereo (2 channels) aac also suffers from this low volume issue? Or it only happens to 5.1 channel audios.
