Description of the bug

I'm trying to play 2 videos which both have FLAC 7.1 audio on them but jellyfin keeps crashing trying to play the audio. With one of them, it plays for a few seconds then crashes (if you go back it stops at the same exact time), usually by reverting to the first audio in the list but sometimes it gives up after "too many errors" and throws you back to the menu. With the other movie file I have, it refuses to play anything at all.

Reproduction steps

Using the Jellyfin Android app.

What is the current bug behavior?

Movie stops playing the audio every few seconds or not at all.

What is the expected correct behavior?

Movie plays without any issues.

From your limited log I'm afraid this is a client side issue

Quite likely. I just tried one of the videos on Jellyfin Web and it worked as expected.
