How to make audio autoplay on chrome

Solution 1:

Solution #1

My solution here is to create an iframe

<iframe src="audio/source.mp3" allow="autoplay" style="display:none" id="iframeAudio">
</iframe>

and audio tag aswell for non-chrome browsers

<audio autoplay loop  id="playAudio">
    <source src="audio/source.mp3">
</audio>

and in my script

  var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);
  if (!isChrome){
      $('#iframeAudio').remove()
  }
  else {
      $('#playAudio').remove() // just to make sure that it will not have 2x audio in the background 
  }

Solution #2:

There is also another workaround for this according to @Leonard

Create an iframe that doesn't play anything just to trigger the autoplay in the first load.

<iframe src="silence.mp3" allow="autoplay" id="audio" style="display: none"></iframe>

good source for the mp3 file silence.mp3

Then play your real audio file at ease.

<audio id="player" autoplay loop>
    <source src="audio/source.mp3" type="audio/mp3">
</audio>

Personally I prefer solution #2 because it is cleaner approach for not relying so much in JavaScript.

As an alternative we can use <embed>

For Firefox It seems that audio auto-play is working so we don't need the <embed> element because it will create double audio running.

// index.js
let audioPlaying = true,
    backgroundAudio, browser;
browser = navigator.userAgent.toLowerCase();
$('<audio class="audio1" src="audio.mp3" loop></audio>').prependTo('body');
if (!browser.indexOf('firefox') > -1) {
    $('<embed id="background-audio" src="audio.mp3" autostart="1"></embed>').prependTo('body');
    backgroundAudio = setInterval(function() {
        $("#background-audio").remove();
        $('<embed id="background-audio" src="audio.mp3"></embed>').prependTo('body');
    }, 120000); // 120000 is the duration of your audio which in this case 2 mins.
}

Also if you have a toggle event for your audio make sure to remove the created <embed> element for audio.

Note: After your toggle, it will restart from the beginning because the <embed> is already deleted and the <audio> element will play as normal now.

$(".toggle-audio").on('click', function(event) {
    audioPlaying = !audioPlaying;
    $("#background-audio").remove();

    clearInterval(backgroundAudio);
    if (audioPlaying){
        $(".audio1").play();
        // play audio 
    }
    else {
        $(".audio1").pause();
    }

And now make sure to hide these <audio> and <embed> elements

audio, embed {
    position: absolute;
    z-index: -9999;
}

Note: diplay: none and visibility: hidden will make the <embed> element not work.

Solution 2:

There is a really neat trick to use the autoplay-function of the audio tag in chrome.

Add

<iframe src="silence.mp3" allow="autoplay" id="audio"></iframe>

whereas silence.mp3 only is 0.5 seconds of silence.

This

<audio id="player" autoplay controls><source src="0.mp3" type="audio/mp3"></audio>

works afterwards.

Chrome notices that a sound has been played and gives the permission for autoplay in audio tags.

Solution 3:

As of April 2018, Chrome's autoplay policies changed:

"Chrome's autoplay policies are simple:

Muted autoplay is always allowed.

Autoplay with sound is allowed if:

User has interacted with the domain (click, tap, etc.).
On desktop, the user's Media Engagement Index threshold has been crossed, meaning the user has previously play video with sound.
On mobile, the user has added the site to his or her home screen.

Also

Top frames can delegate autoplay permission to their iframes to allow autoplay with sound. "

Chrome's developer site has more information, including some programming examples, which can be found here: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes
