Audio on layers as well as base layer

Hi,

I have a slide that has a base layer with buttons.  I have audio created on the base layer, but also on the individual layers that show when the buttons are clicked.  Of course, if the user clicks the button before the base layer audio is complete, both audio tracks play at the same time.  Is there a way to keep the layers from appearing (even if the button is clicked) until the base layer audio completes, or to stop the base layer audio if the learner clicks the buttons?

Thank you!
