[Silvia Pfeiffer]

Just a further note on this since I have received a few private concerns:

audio.ogg is for a Ogg Vorbis file in the traditional sense - an Ogg
file with only one Vorbis I track and nothing else. Future Ogg Vorbis
files are supposed to have a Skeleton track which will help better
identify the codecs inside the Ogg file. Such Ogg Vorbis/Skeleton
files will be called audio.oga to distinguish them.

A similar argument applies to Ogg Speex files.
