I'm creating an iPhone app and part of my app allows for the playback of remote audio files. I've created two buttons - one to play an audio file and one to pause an audio file.

var url = "http://www.mydomain.com/path/to/file.mp3";

// load from remote url
var sound = Titanium.Media.createAudioPlayer({
    url:url,
    audioSessionMode:Ti.Media.AUDIO_SESSION_MODE_PLAYBACK
});

var play = Titanium.UI.createButton({
    ... play button properties here ...
});

play.addEventListener('click', function()
{
    sound.start();
});

win.add(play);

var pause = Titanium.UI.createButton({
    ... pause button properties here ...
});

pause.addEventListener('click', function()
{
    sound.pause();
});
win.add(pause);

Also, in my info.plist to allow the audio to keep playing when a user exits the app, I have the following:

<key>UIBackgroundModes</key>
<array>
<string>audio</string>
</array>

As far as the audio playing in the background and pausing it's working great. What I can't figure out is how to make the system iPod control (the control when you double-click the home button and swipe all the way to the left - where you see the orientation lock, rewind, play/pause, forward, and current playing app icons) pause and start the audio playing.

Any help is greatly appreciated!
