Javascript Denshion Sample plays sound effect only 5 times

In Javascript samples 3.0RC0 in the CocosDenshion tests I can only play the sound of an effect for 5 times. Then it stopps. The same in my app. I have to call stopEffect() every time I use playEffect(), but I don’t know why. Is this a bug or a wrong usage?

var effectId = cc.audioEngine.playEffect(res.plopp_mp3);

stopps after 5 times unless I call

cc.audioEngine.stopEffect(effectId);

The MP3 is made with Audacity/lame

It’s due to am update of browser’s audio API, the old audio terminate callbacks stop to trigger, we will fix it in next release
