I've been building a web application which I'd like to work natively in the webOS web browser. It uses the HTML5 audio tag to play a sound effect.

I found a particularly helpful site which shows your browser's support for the audio element. When loaded on my Pre it says "This browser supports the <audio> tag" but it can't play mp3, wav, ogg, au, snd, aif, aifc, or aiff.

Are there any audio files which can be played this way?
