Playing external device sounds

In addition to playing device sounds that are bundled in the published SWF file (see Using bundled device sound), you can also load and play external sound files. To play external device sounds you use the loadSound() method of the Sound object. As with bundled device sound, the Flash Lite player passes the externally loaded audio to the device to decode and play.

The following information about playing external device sounds in Flash Lite 2.0 is important to remember:

Unlike in the desktop version of Flash Player, externally loaded sounds in Flash Lite 2.0 are always treated as event sounds. This means that external device sounds do not stream--that is, play as they are being downloaded. The sound data must download fully before you can play the sound. For the same reason, you must call the Sound object's start() method to play the sound once it is fully loaded (see the following code example).
The Flash Lite 2.0 implementation of the loadSound() method does not support that method's second parameter (isStreaming). Flash Lite ignores this parameter if it is present.
Flash Lite 2.0 does not play externally loaded MP3 files natively. If your application loads an external MP3 file, Flash Lite passes the sound data to the device to decode and play, as it does with any externally loaded sound file.

The following code shows how to load and play an external sound file:

// Create the sound object.
var mySound:Sound = new Sound();
// Define onLoad handler for sound,
// which starts the sound once it has fully loaded.
mySound.onLoad = function(success){
    if(success == true) {
        mySound.start();
    }
}
// Load the sound.
mySound.loadSound("http://www.macromedia.com/audio.midi");
