Sound objects won't play when loaded onto a level

I have sound objects in my movie that are working fine, but when I load the swf into a level in my base movie the sound objects stop playing.

Here is what I am doing.

Level0 is the base movie.
I load my swf with the sound objects onto level 1.

In my swf file on level1 frame 1 I have an action that says

stop();
_visible = false;

On the layer above my actions layer I have an other layer with a key frame in frame 1 that defines the sound objects.

When I take out the

stop();
_visible = false;
the sound objects play.

Am I doing something that I am not supposed to be doing?

Please help
