add audio attribute to video element
Last modified: 2010-12-12 18:56:45 CET
The audio attribute on the video element controls the default state of the audio channel of the media resource, potentially overriding user preferences.
The audio attribute, if specified, must have a value that is an unordered set of unique space-separated tokens, which are ASCII case-insensitive. The tokens must be from the following list (currently, only one allowed token is defined):
Causes the user agent to override the user's preferences, if any, and always default the video to muted.
A future version of this specification will probably introduce new values here, e.g. to control the default volume, or to select a default audio track.
