How to enable autoplay and sound in video+html5?

Question

Joomla

Good afternoon, tell me please:
I open the video, but it has no sound ...

<video id="vidos" class="img-fluid" muted preload="auto" autoplay="true" loop="true">
    <source src="/images/Silestone450.mp4" type="video/mp4">
  </video>

I'm trying to add JS:

<script>
jQuery("#vidos").prop('muted', false);
</script>

autoplay doesn't work at all.
I need to implement autoplay video on the site, but the sound is required. How to deal with it?

Answer 1

So remove the muted attribute from the code.

<video id="vidos" class="img-fluid" preload="auto" autoplay="true" loop="true">
    <source src="/images/Silestone450.mp4" type="video/mp4">
  </video>
