Disabling sound on buttons

Hi all,

I’ve been working on someone elses old flash movie. It contains ye olde button symbols, you know, the ones with ‘up, over, down, hit’ frames. The buttons produce a sound when you go over them because they have a sound in the ‘over’ frame.

My question is: how do i disable these sounds? There is no soundObject that i can setVolume, and the buttons themselves cant be disabled.

Is there a way to affect the global volume of a flash movie?

Thanks for your time,
Simon
