3 years ago I did some more testing today and this is still a problem with Firefox 90.0.2 and Jellyfin 10.7.6. I also tested with Chromium 90.0.4430.85 and had the same issue except the stall point was at 4m20s instead. It seems like the buffer is a different size in different browsers.
I also noticed that it was more intermittent this time around. Some files would work at first then stop working later then start working again, as long as I switched tracks between playbacks.
I think the bufferFullError is a red herring and that the relevant message in the first screenshot is actually the "FFmpeg audio error:-1313558101" which according to a google search is a generic unknown error. There's something wrong with the audio data being streamed to the browser which is causing it to fail to decode it.
I grabbed all the *.ts files out of the transcode directory during a failed playback and was able to play each one in a standalone player back to back. I also ran ffprobe on each of them and didn't get any errors so I don't think there's anything wrong with the transcode itself.
My best guess is that the audio data is sometimes getting corrupted when appending to a previously full buffer but I'm not sure how to troubleshoot further from here.

Describe The Bug
When playing back some lossless AIFF music tracks on Firefox the progress bar initially loads up to 5m29s. As playback approaches this point or upon seeking to a point just before it, the progress bar finishes loading the track. However, when playback reaches 5m29s the music stalls and no further seeking, pausing, or resuming will restart the music. The only fix is to skip to a different track.

Additional Context
This has been a problem for awhile (probably months, I'm not sure exactly when I first noticed it).
Jellyfin is running in Docker with the official jellyfin/jellyfin image behind an nginx reverse proxy.
The track is being transcoded by Jellyfin. I've attached the transcode log above.
Only lossless AIFF's are affected (MP3's work properly) but oddly enough some AIFF's work properly as well. If a track has this issue then it will always have it and if a track doesn't then it will always work properly.
It's possible to work around this issue by seeking to a point after 5m29s then seeking to a point before it. Then playback will no longer stall (for this particular playback).
