Audio-ISSUE-55 (HTMLMediaElementIntegration): HTMLMediaElement integration [Web Audio API]

The section "Integration with the audio and video elements" should be merged into the definition of MediaElementAudioSourceNode. Unfortunately, the combination of the two still leaves the behavior completely undefined, with only an example given and no normative requirements for implementations.

What happens when a HTMLMediaElement

 * has readyState HAVE_NOTHING?
 * is paused?
 * is seeking?
 * has no audio channels?
 * switches the active audio channel using the AudioTrack.enabled interface.
 * is muted?
 * has volume < 1?

Finally, should the HTMLMediaElement still be producing audio output, or does the MediaElementAudioSourceNode consume the output?
