Digital Workshop

Hi, I am using creator 9.02 and opus v7 and my question applies to both,

I have a multiframe with hidden text on different frames and sound attached to those text as “pre show” action. The multiframe is hidden because I don't want to use it at the beginning of the exercise, but because I have buttons actions ordering to show those texts of that multiframe, as part of other commands, the sounds attached to the texts are playing even with the multiframe hidden.
Is there any way to prevent the sound playing when the multiframe is hidden?
