Help adding a volume control to buttons

I’ve been looking around and searching to see how I can add a volume slider that controls the sound of the buttons on my site. They only make noise when you roll over them or click on them and I want the user to have to choice to turn off the sound or turn down the sound if they want to. I followed the “Creating a Volume Control Slider” tutorial http://www.kirupa.com/developer/mx/volume_slider.htm and I can’t get it to coorespond with the sounds of my buttons. Is this even possible? I’m pretty new to flash so any help I can get would be great! :puzzled:
