HTML audio tag volume
Theres no volume attribute supported by browsers so you must set the volume property in JavaScript <audio autoplay id=”myaudio”> <source src=”http://lel.com/link/to/stream.m3u”> </audio> <script> var audio = document.getElementById(“myaudio”); audio.volume = 0.2; </script> See http://jsfiddle.net/sjmcpherso/6r1emoxq/
