Hi,  
  
I'm working with PTB version 1.0.5 for OSX. I'm creating a movie that shows two disks   
moving along the screen, and need to play a sound at various points of the movie.  
  
I tried using the Snd function but that pauses at the point where the sound has to be   
played (even if I open the channel before the movie starts). I read on a post here that   
audioplayer gets rid of this pause; the pause did go away, but I can't get audioplayer to   
play the sound at the exact same time across multiple runs of the movie.   
  
The Snd help mentions that I can create a soundtrack for the movie and start it before I   
start the movie. I'd like some help on creating the soundtrack using PTB functions. Any   
suggestions on other sound functions would also be helpful!  
  
Thanks,  
Swetha.
