Let’s talk about some of the problems I have summarized after inserting audio files into html (playing mp3 files) through my local testing:

1.
Problem: It works fine on IE8 (played through the media player plug-in) but will not play on IE6 and IE7
On Firefox, you need to install the QuickTime plug-in to play
Chrome By converting it into the tag on html5, it can be played but the entire screen will blue screen
Opera will not play automatically

2.
Problem: It will not play normally on IE6, IE7, but it will play normally on IE8
It will work fine on Firefox
Chrome requires a dirty QuickTime plug-in to play normally
Opera will not play automatically
