Music problem in Cocos2d-Js

Greeting,
I’m having trouble adding music. In gamemenager.js in RES I added this line of code

res.Main_Music = "MojWeb/Cocoslite/sound/zvuk.wav";

And then I added this line of code to game.js

cc.audioEngine.playMusic(res.Main_Music, false);

And not working… :frowning:
