Play Sound Effects Bug in Web? JSB

Hello guys,

I am developing a game on the new HTML5 engine and I have troubles with playing sound effects. When I make a build in a studio (Cocos Code IDE Build:V1.0.0.RC1) sounds play fine, but when I make a build in a web browser (Google Chrome, Mozilla Firefox) each kind of sounds play only 5 times, but then never play again.
Here is the consol`s output:

I am using MP3 file format.

For playing sounds I use the following code:
this.audioEngine = cc.audioEngine;
this.audioEngine.playEffect(res.SoundStarBurst_mp3);

Is it a bug? Or maybe I am doing something wrong?

In release all works well.
