I have been experimenting with the audio tag on my site, and it seems
to me that the current [audio] tag implementation is very good at
embedding long-form audio files (podcasts, songs, etc), but almost
useless for short sound-effects (gunshots in a game, the "click" of a
button, etc). This limits its usefulness in what I was trying to
achieve.
If anyone is interested, the results of my experiments are here:

I wrote a short blog entry about my experiences here:
