A player can select only audio and subtitle tracks supplied for the chosen item. An app preference does not create a missing language track or subtitle file.
Choose an audio track
Open the playback audio menu and select an available track. If a track has no sound, compare another track and another item, then check the TV or sound-system output.
When subtitles are not visible
- Check whether the item actually supplies a subtitle track.
- Enable that track in the player.
- Check subtitle visibility settings such as size and colour where available.
- Compare a second item before treating the player as the cause.
Describe the missing option
Report the title, available language options, selected track and player version. A missing option across one item may be a source limitation; a missing control across all items may be a player feature or licence limitation.
