The audio is mp4. There would have to be wave or webm version for Firefox to play it.

This is basically the equivalent of bug 541286 for audio I think and is therefore presumably equally WONTFIX.

FFx 4.0 plays mp4. This is the background sound in the example (link fetched from the source code): http://ie.microsoft.com/testdrive/Performance/SantasWorkshop/media/song.mp4

Since bug 541286 was set to WONTFIX several changes were made (see comments)

Gecko doesn't support mp3 or mp4 as <audio> tag, only ogg is supported.
mp4 might be supported via plugin but a plugin isn't used for <audio> or <video>
