Identify what is missing from the experience
Yle names Avara luonto, Prisma and history documentaries as programmes that may offer Finnish narration alongside original-language sound. Its caption help explains that a viewer hearing no Finnish narration and seeing only some subtitles should check that Finnish is selected as the receiver’s primary audio language.
Listen for the narrator separately from interviews or dialogue. Write down whether the issue affects the explanation between scenes, a person speaking on screen, or every voice. Those are useful observations because a Finnish narration option and translation of every word in an original soundtrack are different editorial components.
Compare the audio choice with the intended version
Open the receiving device’s audio options and read the available labels for that programme. Use the device manual for its own controls; a remote button and a persistent language preference may be presented differently. Keep the original setting in your note before selecting the intended narration.
An illustrative household comparison should use the same documentary passage. Check whether changing the selected audio changes the narrator while keeping the episode and position fixed. Do not use a different broadcast to decide that the first programme has a complete or incomplete translation: available versions can differ by item and receiving route.
Separate narration from programme captions
If you want written Finnish text for Finnish speech, check programme captions as a separate service. Yle distinguishes those same-language captions from translation subtitles for foreign-language material. Selecting Finnish audio does not itself enable a caption track, and enabling captions is not an audio-language change.
If the intended narrator is still absent, preserve the programme title, transmission date, channel, selected audio label and receiving route. A precise report can explain that Finnish audio was selected yet the original narrator remained, or that the available track list contains no Finnish option. That is more actionable than calling all documentary sound a subtitle failure.
