实时丢失音频＆＃34;当前时间＆＃34;

Question

我自己建立一个小型音频播放器。此播放器包含7个按钮，单击时可将歌曲添加到播放列表，然后您可以按播放开始播放。一切正常，除了这一件特别的事情：我随机播放的音频文件丢失了大约1秒钟，而且非常烦人。 我调试了系统，当我删除当前时间播放的实时可视化时，问题似乎消失了。 我认为这是近似的一个问题，但我不知道如何解决。 这就像它试图达到＆＃34;当前时间因为它在Math.floor之后丢失了一些值 这是我的代码：
近似+可视化代码：

function infoSong2(){
    pippo = Math.floor(audioElement.currentTime);
        pluto = Math.floor(prova);
        var pippo2 = minutesModafaka(pippo);
        var pluto2 = minutesModafaka(pluto);

        $("#info").empty();
        $("#info").html(pippo2+"/"+pluto2);
}
function minutesModafaka(seconds){
        var minutes = Math.floor(seconds / 60) % 60;
        var seconds_left = seconds % 60;
        var time_formatted = (minutes < 10 ? "0" + minutes : minutes) + ":" + (seconds_left  < 10 ? "0" + seconds_left : seconds_left);
        return time_formatted;
    }

音频播放代码：

function playSong(){
        if(arraySongs.length == 0)
        {
            console.log("No songs selected!");
        }
        else{
        clicks++;
        console.log("CLICKS PLAY:"+clicks);
        if(clicks > 1)
        {
            pausePlaySong();
        }
        else{
            audioElement.setAttribute('src', 'audio/'+arraySongs[cont]+'.mp3');
            var p2 = arraySongs[cont].split('g')[1];
           p2 = parseInt(p2);
         $.ajax({
            cache:false,
            type:"GET",
            data:{p2:p2},
            url:"http://localhost/gpio2.php",
            success:function(msg){
                console.log("Connessione avvenuta!");
                console.log(msg);
        }
            });            
            audioElement.currentTime = pause_time;
            audioElement.volume = volume;
            audioElement.addEventListener('loadeddata', function() {
            prova = audioElement.duration;
             });
    audioElement.addEventListener('timeupdate', function() {
                 infoSong2();
             });
    audioElement.addEventListener('canplaythrough', function () {
            console.log("Audio load complete!");
            audioElement.play();
            });
            nextSong();
        }
        }
    }


        function nextSong (){
             if (cont < arraySongs.length) {
             audioElement.addEventListener('ended',function(){
                 cont++;
                 console.log("ArraySongs[cont]: "+arraySongs[cont]);
                 if(arraySongs[cont] == undefined)
                 {
                     var p5 = arraySongs[cont-1].split('g')[1];
                    console.log("Playlist complete!");
                    this.removeEventListener('ended', arguments.callee);
        repeatSong();
                 }else{
                 var p3 = arraySongs[cont].split('g')[1];
                 var p4 = arraySongs[cont-1].split('g')[1];

         $.ajax({
            cache:false,
            type:"GET",
            data:{p3:p3},

            success:function(msg){
                console.log("Connessione avvenuta! "+p3);
                console.log(msg);
        }
            });
             audioElement.setAttribute('src', 'audio/'+arraySongs[cont]+'.mp3');
    audioElement.addEventListener('canplaythrough', function () {
            audioElement.play();
            });
                 }
                })

             }  
        }
function jackInserted(){
        $.ajax({
            cache:false,

    setInterval(jackInserted,999);// The PHP page send me 1 if the jack is inserted, 0 if not.
