Write down the desired viewing combination
Decide whether you want original audio, French audio, subtitles or a particular combination. Those are separate components of a viewing preference. A programme’s production country and the language of the app interface do not settle which version the service has licensed.
For example, a viewer studying a language may find a familiar international series but still need to confirm its original audio. Someone sharing a screen with a French-speaking family member may prefer another combination. Resolve the requirement before planning a session around artwork or a general catalogue category.
Inspect the programme’s version control
The official help says a version button appears at the upper right when the programme has the relevant alternatives, allowing VO or VF and subtitle activation. If the original version is absent, the page gives rights and content-producer agreements as possible reasons.
Treat the missing alternative as a programme-availability question before changing account interface language. A setting can choose an offered version; it cannot demonstrate that an unlisted track has been licensed. Record the title and episode because another item in the same series or catalogue may present different choices.
Plan the session around the available edition
If the intended audio is essential, check another legitimate title or ask M6+ support about the exact programme. Do not assume an upgrade will add a track without a current offer stating that result. Keep any subscription decision separate from the visible audio choices.
A useful support note includes title, episode, device, available version labels and the combination you expected. That describes the actual gap without claiming all original audio has failed. This article interprets the official VO/VOST help and contains no language-switch, title-licensing or playback test.
Questions about this guide
Does every international programme have original audio on M6+?
No. The help says rights can prevent VO availability.

No. Check the programme’s offered version choices.
