enableAudioVolumeIndication不生效

用的是这个网址的版本
我cocosCreator引擎是 2.0.9

代码

    agoraCreator.createEngine("xxxxx");// input: APPID
    agoraCreator.agoraCreatorInst.setChannelProfile(2);
    agoraCreator.agoraCreatorInst.setDefaultAudioRouteToSpeakerphone(true);//外放
    agoraCreator.agoraCreatorInst.setVoiceOnlyMode(true);//消除噪音

    agoraCreator.agoraCreatorInst.enableAudioVolumeIndication(200, 3);//监听用户

agoraCreator.agoraCreatorInst.onAudioVolumeIndication = function (speakers, speakerNumber, totalVolume){
console.log("[js]onAudioVolumeIndication, speakerNumber:%d, totalVolume :%d !", speakerNumber, totalVolume);
if (speakerNumber == 0) {
console.log("[js] callback of Remote Speakers");
}

        for (var i = 0;i <speakerNumber; i++) {
            if (speakers[i].uid == 0 && speakerNumber == 1) {
                console.log("[js] Local Speaker[%d], uid:%d, volume : %d", i, speakers[i].uid, speakers[i].volume);
                return;
            }else{
                console.log("[js] Remote Speaker[%d], uid:%d, volume : %d", i, speakers[i].uid, speakers[i].volume);
            }
        }
    };

但是 我加入频道后 两个人对话 日志并没有打印 证明方法没有调用
如何解决

agoraCreator.agoraCreatorInst.enableAudioVolumeIndication(200, 3);//监听用户
返回值 是 0 但是 onAudioVolumeIndication 的消息 没有触发
