Volume Control

Hi i was trying to make a soundbar control with the tutorial that appears in this page:

http://www.kirupa.com/developer/mx/volume_slider.htm

But there’s a problem, when i play the swf movie, the sound starts in the 0% of volume, i want it to be in the 100% because if it doesn’t, it will be never be listened.
How can i change that?
And in the other hand, i will like that the play button could change into a pause one and make the action of pause the music, not to stop it.

Hope you answer soon.
Thank you a lot!
