question about stopping audio

Having trouble figuring out how to stop a sound that's playing.

example would be a 20second loop of music is triggered on start of layout. but the player dies while the music is playing. the layout reloads "go to layout" other instance of the music starts to play on top of the old.

What's a good way to stop a sound currently playing?

thanks.

The next build (should be out tomorrow) has a "stop" action for Audio!

Awesome thanks for the reply.
