I have built an app, designed to play each sound as the first one is finished by using 'ended' event.
In my initial version, each sound has its own audio element, resulting in something like:
function play_next_audio(){
speaker = $('audio#' + sounds[i++]).get(0);
speaker.addEventListener('ended',play_next_audio);
speaker.play();
}
This works great on all desktop browsers, including Safari, but does not go beyond the very first letter on iOS.
I have also tried a different approach - a single audio element that loads each sound in turn. There I experimented with binding the 'ended' event as well as loading first and binding 'canplaythrough' event instead. In both cases, it fails to work even on the desktop Safari - this time successfully playing the first two letters.
Here is the isolated test:

Note that audio.load() is commented out several places - having it in or out seems to make no difference.
What am I doing wrong? How can I play series of sounds on iOS? Thank you so much for the help!
update As of 2017, the ended event doesn't fire on Safari (or Chrome) on iOS under several conditions. More information can be found here: It's almost 2017, and HTML5 audio is still broken on iOS .
I've built an HTML5 audio player ( Chavah Messianic Radio ) that "works" on Safari on iOS.
By "works", I mean, it plays the best it can on Apple's crippled iOS <audio> implementation. At the time of this writing, this includes iOS 5. I've tested this on iPhone 3 and up, and iPad original, iPad 2, and iPad 3.
Here are my findings:
Hope this helps.

In the meantime: Apple, please, please, please give us better support for HTML5 in iOS Safari . Here are your action items, Apple:
Do those things, Apple, you'll be the industry leader in mobile HTML5 audio, everyone will emulate you, you'll once again be leading the way, and web apps will work perfectly on your platforms, while being crippled on other mobile platforms. Yes, these features will use data and the battery, but native apps already do this. Stop crippling web apps and be the leader. Make HTML5 <audio> a first-class citizen on iOS.

I don't believe the .play() method is supported for audio or video in iOS. Apple does not like the idea of videos or audio automatically playing upon visiting a page.
