HTML5 audio playback over HTTPS on safari IPhone 4.3

Question

I have written a simple HTML code to play an audio file using the HTML5 audio tag on IPhone.

Answer 1

This was mentioned above by ceejoyez and again by the OP (Thank you both!), but I almost missed it as it wasn't an actual answer:

If you are serving the content over https you need to have a valid certificate or it will not play on iOS devices (or on Safari on a Mac).
