[google-chrome] How to make audio autoplay on chrome

i used pixi.js and pixi-sound.js to achieve the auto play in chrome and firefox.

<script>

            PIXI.sound.Sound.from({
            url: 'audios/tuto.mp3',
            loop:true,
            preload: true,
            loaded: function(err, sound) {
                    sound.play();

            document.querySelector("#paused").addEventListener('click', function() {
            const paused = PIXI.sound.togglePauseAll();

            this.className = this.className.replace(/\b(on|off)/g, '');
            this.className += paused ? 'on' : 'off';

            });
            }
            });

</script>

HTML:

<button class="btn1 btn-lg off" id="paused">
    <span class="glyphicon glyphicon-pause off"></span>
    <span class="glyphicon glyphicon-play on"></span>
</button>

it also works on mobile devices but user have to touch somewhere on the screen to trigger the sound.
