Unable to play shows with TrueHD audio

[appletini]

Hi all, I've been ripping my anime collection and re-encoding it as part of my upcoming home server setup but I'm being unable to play any Shows specifically.

I'm currently putting both Movies and Show in a Mixed Library, which seems to be working for films, but not series. I've also tried moving these series to a Shows specific library and that also doesn't work.

I'm re-encoding all my files with the exact same Handbrake custom preset and have not had any issues so far, with the exception of these two shows.

The only major difference I can notice is that these two shows have TrueHD audio, so unless Jellyfin is currently unable to reproduce this codec, I'm at a lost and I don't know what else I can do/try.

Thanks in advance for any help!

We discourage the use of Mixed libraries. It is a legacy feature that isn't well maintained. And there will be frequent issues with identification.

But to your problem, can you share your full jellyfin log via pastebin?

Could you please elaborate? I'm not sure I understand. 

I have another film with TrueHD 5.1 that works fine but the files that are TrueHD 2.0 are the ones giving me issues.

But to your problem, can you share your full jellyfin log via pastebin?

Posting it here as this seems to be the only output I'm getting in the log regarding this playback.

Code:

Mixed libraries frequently have issues correctly identifying shows and applying the correct sort of them. Shows are identified as a bunch of movies, movies as 1 episode shows, specials for a show not shown, etc.

Some people have gotten mixed libraries to behave properly, but they are the lucky few.

So your log indicates it is direct playing, so any issues are client side. I don't have any 2.0 TrueHD content for testing. Only DTS-MA 2.0 content, which is always transcoded to AAC.

What kind of Android TV device is it? Can you the Jellyfin client's audio settings? Is it configured to pass through? Is it configured to downmix or is it set to direct?

I have also tried moving these shows to a bespoke Shows library but still didn't work.

I kept all the original audio on all my re-encodes and haven't had any issues so far. All the content is in TrueHD 5.1, PCM 2.0 or DTS-HD MA 5.1, and none of them have issue. Only TrueHD 2.0.

The TV is a Sony Bravia XR-55A84K and the audio settings are set to "Direct" audio output.

Edit: I've uploaded a small snippet of one of the files here if you wouldn't mind testing it on your end? I can open the file, seek the timeline and see the frame but it never actually plays continuously so I don't even get to hear any audio.

Can you run this command and share the output?

Code:

/usr/lib/jellyfin-ffmpeg/ffprobe -loglevel error -i "/path/to/you/video.mkv" -select_streams a -show_entries stream -v quiet -of json

Everything looks normal.

I added your clip to my test Jellyfin instance and I will try playing it when I get home.

Huh. Also happens on my CCwGTV 4k. The only workaround I could find was to either select a really low bit rate to trigger transcoding or going to the Playback settings in the Android TV app and setting the audio output to "downmix to stereo", which also triggers transcoding (but just the audio this time). I'll report this bug on github.
