Audio and subtitles are separate tracks with their own selections and availability. Changing one does not necessarily change the other. A player’s preferred-language setting may guide automatic choices, but the programme must actually contain a matching track for that preference to be satisfied.
Inspect the current selections
Open the audio menu and subtitle menu during playback. Look for the chosen language and any descriptive or commentary label. Do not rely only on the channel’s country category, because a particular programme can carry a different original language, a dubbed version or several alternative mixes.
Set preferences without assuming availability
Choose the household’s preferred audio and subtitle languages if the player supports defaults. Then test another programme and a fresh playback session. Some apps remember choices per title or per channel, while others apply a global preference. A missing track cannot be created by selecting a language in the interface.
Describe missing options clearly
When asking for help, state whether the language is absent from the menu, selectable but silent, or present under an unexpected label. Include the programme and selected player. Those are different problems. Do not send account passwords or assume reinstalling the app will add a language that the source does not carry.
