Change Language

Which client are you using?  Jellyfin Media Player or a browser?

If this is a web-based client, like Jellyfin Media Player, Android or iOS, there is a setting that changes how Jellyfin selects tracks.

If the audio track is marked as default or forced, depending on how you have the client configured, it will play that track and ignore your language preference.  In the above web based clients, you can tell Jellyfin to ignore "default" tracks and play your preferred language.

Settings > Playback > Play default audio track regardless of language
