*
* <ul>
* <li>A forced text track with unknown language if the selected audio language is also unknown.
* <li>A forced text track matching the selected audio language.
* <li>A default text track matching the selected audio language when a default text track in

* track in the selected audio language is not present (but other text tracks in this
* language are present).
