Why audios in layers don´t sound (sometimes)?

Hi, I created a soccer game that goes as follows: when you click a ball, it moves with a motion path; when this motion path ends, it opens a layer with a video (a ball hitting the net) and audio (the exclamation "gooal"); the problem is that sometimes the audio in the layer is heard, sometimes not. I set this layer and the base layer in "Reset to initial state". The base layer also has audio. It seems as if the audios and/or the video compete and one blocks the other, or something, but only in some occasions. Any clue? Can I share my file privately to someone of the Articulate staff? Thanks.
