[10.8.0-1.4.13 Regression] Alternative audio tracks no longer played

[jcdick1]

Describe the bug Using "Options" on a movie title with multiple audio tracks, selecting a non-default audio track isn't acknowledged. The default is played.

To Reproduce

1. Select a movie title with multiple audio tracks
2. Navigate to and select "Options" then "Audio"
3. Select an audio track other than the default
4. Back out and play the movie
5. The track played is still the default

Expected behavior The alternate audio track should play

Logs

JF log entry for attempting playback on a movie with two audio tracks, keeping the default audio track selected:

[2022-06-13 11:27:42.062 -05:00] [INF] StreamBuilder.BuildVideoItem( Profile="Anonymous Profile", Path="/mnt/media/video/movies/fun_movie.mkv", AudioStreamIndex=2, SubtitleStreamIndex=-1 ) => ( PlayMethod=DirectPlay, TranscodeReason=0 )

JF log entry for attempting playback on the same movie, selecting the second track:

[2022-06-13 11:18:54.916 -05:00] [INF] StreamBuilder.BuildVideoItem( Profile="Anonymous Profile", Path="/mnt/media/video/movies/fun_movie.mkv", AudioStreamIndex=3, SubtitleStreamIndex=-1 ) => ( PlayMethod=DirectPlay, TranscodeReason=0 )

Note that it is setting "AudioStreamIndex" as "2" for the default track, and "3" for the alternate track. There are only two tracks. Honestly, don't know if this is related, but it seems like it would be 0 and 1 or 1 and 2.

Additional context

Since 10.8.0 dropped fairly quickly after the Roku 1.4.13 release, I didn't have occasion to view any of my content containing alternative audio tracks between those two releases. I don't know if this is a 10.8.0 compatibility issue, or if it is something that changed with all of the additions to 1.4.13 itself.

Update: I have found some that do work. Those that do have their tracks identified as above, for AudioStreamIndex, as 1 or 2, depending on default or alternate audio. However, all files are encoded the same, with the same software. I can't figure out why it would now be identifying files as having audio stream 2 and 3. But its only on the Roku that I have an issue with playback.

I have tested this an cannot get the same issue. Is this still happening?

[jcdick1]

Yes, it definitely is still happening. Oddly, on my Firestick 4K, the logged "StreamBuilder" line in the log when playing back this same title and second audio track is:

[2022-06-16 10:54:49.160 -05:00] [INF] StreamBuilder.BuildVideoItem( Profile="AndroidTV-libVLC", Path="/mnt/media/video/movies/fun_movie.mkv", AudioStreamIndex=null, SubtitleStreamIndex=null ) => ( PlayMethod=DirectPlay, TranscodeReason=0 )

Note the "AudioStreamIndex" being "Null" instead of "3".

[candry7731]

hmm, I would assume this is a server issue and not a roku specific issue....

Does the firestick also not play the second audio track?

[jcdick1]

The Roku client is the only one that doesn't. Web, JMP, Android TV (Firestick) all play the second audio track.

[candry7731]

How many other audio files do you have to choose from when it fails?

There's just the two audio tracks in each of these media files. They're movies that I've muxed in an audio track I mixed RiffTrax jokes into. So a 5.1 track (standard audio) and a 5.1+RiffTrax (alternate audio track). I can ffprobe one that works and one that doesn't, if you think that would help. The mediainfo output is exactly the same, though.

[candry7731]

Hmm, I'm not sure.... We get the index of the audio file in the list and that's what we use to grab the file.... if the ffprobe fails on one track I would think there is a track problem but then you said you can play in all the other clients.... What is the file format for both audio files? Can you share the files with me?

They are VP9 video w/ 2 opus tracks ... the RiffTrax audio is mixed in Audacity and the output muxed with MKVToolNix after the main video and original audio are transcoded.

Here's ffprobe output from one of the problematic ones:

To me, they look the same, but the StreamBuilder log entries shows the first one trying AudioStream=3, whereas the second one uses AudioStream=2, which would make sense.

It may well be something server side, as I added the problematic ones following the 10.8.0 upgrade, but I don't know what they may have changed in terms of how the server handles parsing tracks or building streams based on clients' profiles or whatever that would make it work for video files added prior to 10.8.0 but not after.

I have the exact same issue with my Firestik 4K and 10.8.1, I can't switch between audio languages, the first audio keeps playing

I believe this is a server bug: https://github.com/jellyfin/jellyfin/issues/7896

I can not recreate this issue using latest server and roku client versions. Closing for now, please open a new ticket and ref this on if issue remains.
