Hi Graham, audio and video tracks can be activated the same way that text tracks are, except there is no browser-provided default UI, so the JS developer has to do that. AudioTrack has 'enabled' http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#dom-audiotrack-enabled and VideoTrack has 'selected' http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#dom-videotrack-selected . HTH. Also note that Bob has made a small change to the new spec and updated the caption selection part: http://rawgit.com/silviapfeiffer/HTMLSourcingInbandTracks/master/index.html Cheers, Silvia.
