WAV file embedded for PMs

[CoreyT]

Hello, I co-own and admin a Toyota 4Runner & truck forum called YotaTech.
I am not a coder, and will be looking for help in the future to add the PM blinking toolbar, and also the quick reply box down the road.

But for now I had an idea.
I often embed WAV files on my personal website with the following code:
<embed src=http://www.pnw4runners.com/temp/mail.wav autostart=true volume="100" hidden=true>

I am wondering if for the PM template that pops up the message that says you have a new PM waiting, and if you'd like to open it up in a new window, if I can put the above html code into it to make the mail WAV file play.

I saw the template the other day in my admin section, but now I am having a hard time finding it

Do you think my idea would work?
And if so, where in the heck is that template?
I can see the PM template section, but I can't find the one I saw the other day with the pop up info on it.
