Put a blank slide in front of slide one with zero timings, and link back to it

 I have hyperlinked Slide 1 and Slide 2. Each slide has sound embbeded on it.
 In presentation when I click Slide 1 object, it takes me to Slide 2, and I
 hear the sound, but when I click an object in the Slide 2, while it takes me
 back to Slide 1, but it dosen't play the sound; subsequently, when I go to
 Slide 2, the sound doesn't play! It seems that whne I loop the sildes, the
 sound plays only once! Is there any way to make the sound play as many times
 as the slides are revisted?
