[Media] Separate output

Shane:

Per our discussion on today's call, the requirement to be able to direct
different audio content to different devices is captured in VD-11:

   [DV-11] Support the simultaneous playback of both the described and
   non-described audio tracks so that one may be directed at separate
   outputs (e.g., a speaker and
      headphones).
       
       While I believe directing these separate audio media types has
       always been the intent of DV-11, I think we can clarify and
       further refine this requirement. Here's a suggestion:

          [DV-11] Support the simultaneous playback of both the
	  video description track  and primary audio resource tracks so that either may be
	  directed at separate outputs (e.g., one to loudspeakers and
	     the other to headphones). Where a screen reader is present,
	     also support the ability to keep its audio output separate from
	     both the described video track and the primary audio
	     resource tracks.
