Cross browser play sound button

Does anyone know how (and if it's possible) to create buttons or text that will play a sound on mousedown/onclick/mouseover?

I've tried the examples on this page - http://www.phon.ucl.ac.uk/home/mark/audio/play.htm#, but the only ones that don't make my I.E. browser crash don't work in Firefox.

Any ideas?

I would investigate flashsound.

It's not too hard when you get a handle on it.
