Regardless of whether the spec mandates that the autobuffering attribute  
be set for new Audio(), browsers that want to be competitive on mobile  
will have to be conservative with bandwidth. autobuffering is only a hint  
and doesn't need to be obeyed where it doesn't make sense (in fact can't  
be obeyed because the disk cache is too small).
