cc.AudioManager doesn't exist in cocos2d-x javascript binding

Hi,
I’m currently working on something that is working fine on the cocos2d-iphone js binding but fails with the latest of cocos2dx (2.0.3).
This is not working:
cc.AudioEngine.getInstance();

Am I missing something?

Keep up the great work!

Take a look at https://github.com/cocos2d/cocos2d-x/blob/gles20/samples/TestJavascript/Resources/js/test-cocosdenshion.js
I open the latest code just now, cc.AudioEngine.getInstance() works on iphone6.0 simulator. Which platform are you debugging on?
