trouble with HTML5 audio - please help

Permalink
Hi,
I'm pretty new to coding and could really use some help...
I have used the below code to create an audio player that will work for the different operating systems. The problem is that when I exit editing mode, the player comes up and the status is always "loading." I have the .ogg and .mp3 files in my regular file manager and have tried the name of the file "1 A1 Die Web Q" with and without underscores between the characters. I have included the exact code below. All I want is for a sound to begin playing when the page is opened and for it to be accessible by safari, internet explorer, android, iphone, etc... please help. -thanks

<!DOCTYPE html>
<html>
<head>
<title>Play 1 A1 Die Web Q</title>
</head>
<body>
A1 Die<br>
<br>
<audio controls="controls" autoplay="autoplay">
<source src="1 A1 Die Web Q.ogg" type="audio/ogg">
<source src="1 A1 Die Web Q.mp3" type="audio/mpeg">
