Autoplay audio files on an iPad with HTML5

The only way to make audio play, is through a click event. This wasn't the case on 3.x, but on 4.x it is. This is because Apple doesn't want the webapp to download audio on a 3g connection programmatically, so they force the user to initiate it.

I would think that if all of the tracks were started downloading (cached), then it may be possible. I would try forcing the user to start one track, and at the same time call .load() on all of the other tracks (in the same click handler). This will force the iOS device to start downloading the audio tracks, and you may be able to play the next track (not sure though).
