This issue respects the following points:

  • I have discussed this issue in the Jellyfin forum and/or troubleshooting chat before opening this issue.
  • This issue is not already reported on GitHub (I've searched it).
  • I agree to follow Jellyfin's Code of Conduct.
  • This report addresses only a single issue; If you encounter multiple issues, kindly create separate reports for each one.

Describe the bug

  1. Have this file in your Jellyfin library (https://drive.google.com/file/d/164IB4xe5ZGemclntGLXEVmlD3zO2pcVW/view?usp=drive_link)
  2. Set system language to English
  3. Set "Preferred audio language" to Japanese
  4. Play the file

Expected outcome:
Player plays track 1 (Japanese)

Actual outcome:
Player plays track 0 (English) but the interface shows track 1 (Japanese)

I'm reasonably confident this is caused by ExoPlayer defaulting to system language, because you can reverse the roles of English and Japanese and get it to default to Japanese when English should be preferred as well
