Sound Stop?


On my timeline a have 2 buttons. These 2 buttons are entry points to a presentation, on the same timline. One is for audio and the other for non-audio. my background loop plays on the same timeline, but doesnt start till the buttons are pressed.The two buttons go to the same point.

Cant figure out how to code the non-audio button to pause/stop .sound1(background music), but still play the presentaion?

Please help!
