I've run into something like this a while ago.  Is it possible that this is
an older version of Mac OSX and/or an older version of Rev? In any event, I
got sidetracked and never followed up on it, but I seem to recall thinking
about trying to play silence sporadically to keep the audio busy -- maybe
making a 1 second WAV file of silence to occupy the engine/system and
playing it every so often.  Silence might not be enough to keep the audio
busy, but it's worth a try...

Delay before sound starts playing

[Fred Moyer]

I'm trying to create a stack where the user can play a solo  
instrument along with a sound file that plays an accompaniment. At  
times in the music, the accompaniment stops for a while and the solo  
instrument needs to keep playing; at these places, I've had the sound  
file pause and wait for a mouseclick from the user at which point  
IMMEDIATELY the sound file must play again.  I first made this stack  
back in the Hypercard days and it worked flawlessly. Then I tried to  
move it to Revolution, experienced problems but finally got it  
working with some Rube Goldberg solutions. Now something has  
changed (OSX?, Revolution?, Quicktime?) and it's not dependable. The  
problem is that if there's too long a delay with no input from the  
user, the computer's sound system seems to goes into some kind of  
hibernation mode so that when the user clicks the mouse, there is a  
delay before the music starts again. (I notice that there's even a  
delay in beep in Revolution if the computer has been silent for a  
while.)
