             Summary: Local Audio Failed to Play after an upgrade from 1.9.0 to 2.0.0 on PhoneGap
                 Key: CB-1158
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android
    Affects Versions: 2.0.0
         Environment: PhoneGap 2.0.0. built project with API level 16, minimum API level 8.
It was tested on an Android emulator at API level 10. 
            Reporter: Caleb Qian
            Assignee: Joe Bowser
            Priority: Critical

A local audio file that was named "temp.mp3" cannot be played after the upgrade from version
1.9.0 to 2.0.0. My Phone Gap app was able to play this file upon the version of 1.9.0. 

The audio file was located at "/android_asset/www/temp.mp3".

No sound has been played.
When I manually stop the music by triggering the click event of a "stop" button, the error
function is invoked and "Audio Error" alert message is shown.

Latest update: this was also confirmed in a device deployment. Same behavior as described
above. The device is Moto XT800 running Android 2.2

Here is the log after the "start to play" button is clicked.

Here is the essential section of the code:

function error_error(e) {
		alert('Audio Play Error.');

	function playAudio(src) {
		if (device.platform == 'Android') {
			src = '/android_asset/www/' + src;

		my_media = new Media(src, success, error_error);

						'System is sensing the sensor... Press stop button when you want to stop this process.');

	// play audio main function, callback function and exception handler

	$('#inner_start').live('vclick', function(e) {

		// alert('inner start tapped.');


		return false;

It looks like the app found the file, but there is just no sound being played. I also checked
the emulator, audio playback/recording are both turned on. In addition, I checked /res/xml/config.xml,
the audio handler is there. Permissions also include all necessary configurations such as

I cannot find a difference from the log recorded at a normal playing. I can play online music
through the HTTP URL, but not local audio files.
