Answer 4

My first thought would be to go to Subtitles & Captioning (Settings -> General -> Accessibility -> Subtitles & Captioning Setting) and ensure that ‘Closed Captions + SDH’ is turned off. Even if you set closedCaptionDisplayEnabled to NO, this setting will override it.

You can test if this is enabled on a device within your code using UIAccessibilityIsClosedCaptioningEnabled() which will return a BOOL that is true if it is. However, this setting can not be change within an app.
