audioclips and playstopped

[Richard Miller]

I am having difficulty getting the playstopped message to be recorded  
on a regular basis while playing audioclips. I've got a stack with a  
few dozen pages in it. As the user is taken from card to card, a new  
audio file is played after OPENCARD. Once that audioclip has been  
played, the system should automatically advance the user to the next  
card. To do that, I am watching for the PLAYSTOPPED message. But it  
is not reliable (and I don't know why.. I've not seen any particular  
pattern. Sometimes it works... sometimes it doesn't).

I need to find another way to automatically advance from card to  
card. Suggestions?

I thought maybe I could determine the duration of the audioclip  
before it started to play, then use the SEND command (just before  
playing the audioclip) to advance to the next card once that duration  
had been reached, but I see no way to determine the duration of an  
audioclip (other than hard-coding it).
