Help with sound .fla

[Ecinele]

Could anyone help me with the sound on this button?
I would like to change the sound and I have no idea where the sound is placed.
I even tried changing the name of the sound file contained herein and it doesn't work.
Please help

I would look at 2 things.

1.
In the movie double click on the button
it should open to where you see the states of the button
Do you see the sound in the over or down state ?? Its possible the sound was saved as a movie clip and placed in one of these states.

2. On the work area right click on the button and look in the actions box.
Is the sound called up by actionscript ??
