ненужная загрузка нескольких аудиофайлов при нажатии кнопки воспроизведения ()

Question

У меня есть 2 аудиофайла, но когда я запускаю одну функцию, в этом случае 'setCurTime37 ()' я слышу правильный аудиофайл ('myAudios1'), но он также запускает загрузку второго аудиофайла ('myAudios2'). Это всего 2 файла, на самом деле их 36, поэтому для загрузки требуется много МБ. Я не могу понять, почему это происходит.

<script>
var x = document.getElementById("mymenub").selectedIndex;
var ya1 = document.getElementById("myAudios1");
var loopLimit = document.getElementsByTagName("option")[x].value;
var loopCounter = 0;
ya1.preload = "none"; 

function setCurTime37() {
if ((document.getElementById("precountb").checked==false) && ((ya1.currentTime < 0.1) || (document.getElementById("myAudios1").ended==true))) {
ya1.currentTime = 16.20;
loopCounter = 0;
ya1.playbackRate = document.getElementById("pbr2").value;
ya1.play();
} 
else if ((document.getElementById("precountb").checked==false) && (ya1.currentTime > 0.1)) {
loopCounter = 0;
ya1.playbackRate = document.getElementById("pbr2").value;
ya1.play();
} 
else if ((document.getElementById("precountb").checked==true) && (ya1.currentTime < 0.1)) {
ya1.currentTime = 0;
loopCounter = 0;
ya1.playbackRate = document.getElementById("pbr2").value;
ya1.play();
} 
else if ((document.getElementById("precountb").checked==true) && (ya1.currentTime > 0.1)) {
loopCounter = 0;
ya1.playbackRate = document.getElementById("pbr2").value;
ya1.play();
} 
}

document.getElementById("Pause_sb").addEventListener("click", xx37);
function xx37() {
ya1.pause();
}

document.getElementById("Stop_sb").addEventListener("click", zz37);
function zz37() {
ya1.load();
}

ya1.onended = function() {
var x = document.getElementById("mymenub"); loopLimit = parseFloat(x.options[x.selectedIndex].value, 10); 
if ((loopCounter < loopLimit) &&(document.getElementById("precountb").checked==false)){
this.currentTime = 16.20;
this.play();
loopCounter++;
}
else if ((loopCounter < loopLimit) && (document.getElementById("precountb").checked==true)){
this.currentTime = 16.20;
this.play();
loopCounter++;
}
};

</script>

Не загружайте аудио файлы вообще.Используйте список воспроизведения ссылок.

// Collect all links into NodeList convert to Array
var linx = Array.from(document.links);

// On each iteration add the click event to each link
for (let i = 0; i < linx.length; i++) {
  linx[i].onclick = playlist;
}

// playlist() function -- pass Event Object
function playlist(event) {
  // reference Audio tag
  var player = document.getElementById('player');
  // Get the url of the clicked link href
  var file = this.href;
  // Set Audio src to url of the clicked link
  player.src = file;
  // Load the Audio tag
  player.load();
  // Play the Audio tag
  player.play();
}
