how to turn on captions/subtitles?

Some videos have subtitle languages choices hidden in the
closed captioned settings. This is the reason why
English is not on the list of these available languages.

With Amazon Prime, Netflix, Google Play, Hulu, iTunes and
the Windows Store, one may have to start the video first
and then look for the CC icon in the tool bar.

With the youtube on Android, users must tap on the settings
icon to turn on the captions.

If a video includes closed captions but you do not see them, check the
settings of your device to make sure the closed captions option is
turned on.

Mac operating system and Apple TV set-top box all have caption controls in
their Accessibility preferences. The same goes for Roku and
