Image Map onClick = Location and Play wav sound?

I am trying to figure out how to play a certain sound when clicking on a certain location of an image.

Okay so here is what i am trying to do....

I have the Sonic Characters and when you click on sonic lets say it will follow a url but play a sound. like... Here we go! There is one problem.... If somoene has really really fast internet it wont even play that sound in theory.. it will actually just go to the next page even if sonic says He--. The things I try to do... lol Now it all comes to xml or something to make this work.

I can only modify codes in XML but cant create them. So in theory i am thinking of a code that has something like...

Location id click
Sonic, 1, play='letsgo.wav', wait,2,seconds, target='sonic.html'
Tails, 2, play='herewego.wav', wait,2,seconds, target='tails.html'

Then on the image map it would give an ID like 1 or 2 or 3..

i am just saying that in theory but obviously i have the code all wrong. can anybody help me with this?

Thank you!
