No sound on iOS 6 Web Audio API

Question

I was really excited to see iOS 6 supports the Web Audio API, since we make HTML5 games. However, I cannot get iOS 6 to play any sound at all using the Web Audio API with e

I have come across the audio restrictions with HTML5 Audio on iOS and worked around the problem by:

1) Creating an Audio Element with a silent audio file and playing it initially with a touch event (e.g. 'begin game' button) and then immidietly pausing it.

2) Building a sound-switcher function which switches the Audio src and then plays the Audio element after a short timeout.

3) Calling the sound-switcher function on any events (doesn't need to be a touch event).

This works because the Audio Element is un-muted on first touch, with the silent audio file, and remains un-muted, so the source can be switched on-the-fly.

switchSound: (id) ->
        @soundSwitch.pause()
        @soundSwitch.src = @sounds[id]._src

        clearTimeout @switchSoundDelay
        @switchSoundDelay = setTimeout =>
            # @soundSwitch.volume = 1
            @soundSwitch.play()
