sound transition with reveal.js

Question

I'm learning to use reveal.js and I find it very powerful. I wonder wether it's possible to make reveal play a sound at each slide transition. I made a presentation with the auto-sliding option on and it would be usefull to have a sound when the slide changes. Can someone help me ? Thanks

You can use the data-autoplay attribute for this, it works for both video and audio elements. When this attribute is present on a media element inside of reveal.js that element will play/pause automatically as you enter/leave the slide it lives in.

<section>
  <audio data-autoplay src="yourAudioFile.mp3"></audio>
</section>
