为什么我的不和谐机器人能正常工作但没有声音

Question

我正在尝试创建一个播放来自mp3文件音频的discord机器人。它能够加入语音通道，甚至具有活动指示器，但是没有声音输出。我还注意到根本没有显示任何错误。

我还注意到退出频道需要很长时间。

我的代码：

    static random_vc(client, vchannel){
        if(vchannel==undefined){ console.log("nooo"); return; } 
        var path = "./";
        var myfile = ["1.mp3","2.mp3","3.mp3","4.mp3","5.mp3","6.mp3","7.mp3","8.mp3","9.mp3"];
        var rand = Math.random();
        var i = Math.floor(rand * Math.floor(myfile.length)); //get random index from array
        vchannel.join()
          .then(connection => {
            var dispatcher = connection.play('/path/to/bot/' + myfile[i]);
            dispatcher.on("end", () => { setTimeout(function(){
                console.log("exit chnl");
                dispatcher.destroy();
                vchannel.leave();
            }, 2000) });
         }).catch(console.error);
    }
