        <input type="range" id="vol" max="1" min="0" step="0.01" onchange="changevolume(this.value)"/>

Answer 1

The correct method to set the volume is audioobject.volume = VALUE

Here's a demo showing a similar setup as you want.

 function changevolume(amount) { var audioobject = document.getElementsByTagName("audio")[0]; audioobject.volume = amount; }

 <audio autoplay loop src="https://archive.org/download/animalsounds1/12wolveshowlfar.mp3"></audio> <input type="range" id="vol" max="1" min="0" step="0.01" onchange="changevolume(this.value)" />
