javascript - How to play a sound continuously without break?

Question

I am trying to play a vehicle driven sound in a browser based game (continuously without break).
My .wav file length is 1 second and has same frequency from beginning to end. But sound takes a little break before next iteration.
Here is code:

function playSound()
{
    //alert("");
    myAudio = new Audio('http://ithmbwp.com/feedback/SoundsTest/sounds/tank_driven.wav'); 
    if (typeof myAudio.loop == 'boolean')
    {
        myAudio.loop = true;
    }
    else
    {
        myAudio.addEventListener('ended', function() {
            this.currentTime = 0;
            this.play();
        }, false);
    }
    myAudio.volume = 0.3;
    myAudio.play();
}

Can anyone help me to play the sound continuously?

You can visit my page here to observe the problem.

window.onload = function() {
  playSound();
};

function playSound()
{
//alert("");
myAudio = new Audio('http://ithmbwp.com/feedback/SoundsTest/sounds/tank_driven.wav'); 
if (typeof myAudio.loop == 'boolean')
{
myAudio.loop = true;
}
else
{
myAudio.addEventListener('ended', function() {
this.currentTime = 0;
this.play();
}, false);
}
myAudio.volume = 0.3;
myAudio.play();
}

Use the AudioContext API and its bufferSourceNode interface, to have seamlessly looped sounds.

Note that you'll also need your audio to be correctly edited to avoid crackles and sound clips, but yours seems good.

const aCtx = new AudioContext();
let source = aCtx.createBufferSource();
let buf;
fetch('https://dl.dropboxusercontent.com/s/knpo4d2yooe2u4h/tank_driven.wav') // can be XHR as well
  .then(resp => resp.arrayBuffer())
  .then(buf => aCtx.decodeAudioData(buf)) // can be callback as well
  .then(decoded => {
    source.buffer = buf = decoded;
    source.loop = true;
    source.connect(aCtx.destination);
    check.disabled = false;
  });

check.onchange = e => {
  if (check.checked) {
    source.start(0); // start our bufferSource
  } else {
    source.stop(0); // this destroys the buffer source
    source = aCtx.createBufferSource(); // so we need to create a new one
    source.buffer = buf;
    source.loop = true;
    source.connect(aCtx.destination);
  }
};
