How to play sounds in github?

I was making a github repository with a HTLM5 file and a mp3 file.

On the html file i writed:

<script>
var audio = new Audio('sound.mp3');
audio.play();
</script>

And then i uploaded in the repository a mp3 file, imagine if the file name was sound.mp3.

Here’s what the files look like:

index.html

sound.mp3

The problem is that the HTML script i made is not playing the sound on the github page.

I’m 100% sure that i have the volume up but it dosn’t play.

What can i do to make it play the sound in the repository files?

Also i tried using images and looks like the html can get the img file in the repository but not sounds.
