Why does the attribute "autoplay" not start audio?

I am creating a page where I need to play a sound automatically as background in an infinite loop. The problem is that even using the attribute autoplay, audio does not start.

See below my code:

<audio controls autoplay loop>
    <source src="main_sound.mp3" type="audio/mpeg"/>
</audio>

I’m using the browser Chrome 81.0.4044.92 and also tested in Internet Explorer. In both browsers this property is not working because ?

What I can do to automatically play audio using HTML only ?

html html5-audio

  • You need to provide a valid URL for src audio. You checked this?

  • Yes. Audio plays if I click the play button, but it does not run automatically with the property autoplay.

    Imagine you walk into a website and suddenly there’s the sound of the Black P*rocão playing automatically? Do you understand Pq doesn’t work?

  • It didn’t work. I copied the answer code by taking only the attributes width and height and audio still does not start.

    It won’t work what to do, Chrome as I think all other browsers have modified their auto-play policy all for a better user experience how to read here: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes

  • So how can there be sites where a song or video plays automatically ?
