Movieclip/Audio Help

Hello, this is my first post, no wait, third after I’ve stalked kirupa.com for a while. I’m a Flash animator, and only know very small basics of action script.
I know for example, on how to create a button, stop, and several other things.
Now, I’ve been creating a button to make it play audio.

I’ve made a new movieclip, with the audio in it, streaming (because I need to be able to stop the sound)
But now I can’t seem to find the right action script on making the movieclip play on pressing the button. I believe I did use it at one point back in the beginning of my Flash, but I have totally forgotten how.

Help would be much appreciated.
