You are probably trying to play an unsupported format :)
Firefox 3.6 doesn't support mp3. You can use audioEl.canPlayType() to
detect the available formats like so:
[... snip ...]
AudioElement audioEl = audio.getAudioElement();
audioEl.setAutoplay(true);
if (!audioEl.canPlayType("audio/mpeg;").equals(audioEl.CANNOT_PLAY))
{
audioEl.setSrc("smallmp3.mp3");
} else if (!audioEl.canPlayType("audio/ogg; codecs=\"vorbis
\"").equals(audioEl.CANNOT_PLAY)) {
audioEl.setSrc("smallogg.ogg");
} else {
RootPanel.get().add(new Label("no available media types"));
}
audioEl.setControls(true);
audioEl.setLoop(false);
audioEl.setVolume(1.0);
RootPanel.get().add(audio);
} else {
RootPanel.get().add(new Label("audio not supported"));
}
[... snip ...]
