Is there any reason why PCM in a Wave container has been removed from HTML 5
as a baseline for <audio>?  Authors are currently forced to use plugins to
do simple things like play email notifications (for instance, Gmail uses
Flash for this).  Providing a simple baseline audio codec to handle these
common situations would be a big win.

The reason for not selecting a video codec doesn't seem to have much weight
when considering Ogg Vorbis as a required audio codec.  Apple's submarine
patent argument doesn't seem to hold, as many deep-pocketed companies
(including Microsoft) have shipped products with Vorbis support.  It might
also be worth pointing out that the existing working draft of SVG 1.2
includes a requirement for Vorbis support

Firefox 3.5 will be shipping with support for Vorbis, and I understand that
Opera and Chrome have already shipped development builds with Vorbis
