Audio doesn't work on Safari on iOS

[padovan]

Apple seems to have added some limitation to play to autoplay and/or preload audio on the mobile version of the Safari browser. There is some information in their documentation so we tried the suggestion and other approaches across stackoverflow, etc and it didn't work yet. We also have to take in account that the audio in our case is being playing inside the setTimeout callback, so not sure the documentation is telling the whole story here.

This needs to be investigated further and solved.
