Global way to turn off sound?

Question

My main stage is playing a series of MIAWs and I want a way
to shut down sound channels 1-7, leaving 8 open for sound effects
used by the stage. It's a touch screen application and the client
wants the option to turn off the music but retain the audible
clicks and other sound effects for user interaction.
I've tried setting sound(myChannel).volume = 0 where
myChannel is looped 1-7. I've tried this both in the main stage
just before the MIAW is opened and also in the first frame of the
MIAW itself. I manage to shut down any lingo activated sound but
sound effects dropped into the two score sound channels still play.
I didn't write the MIAW's, I don't want to put conditional tests in
those movies every time a sound is played. Is there a global way to
shut down a specific sound channel that can not be overridden by
the score?

I'll take a couple of stabs at it.
If you're using the sound channels in the score, you may need
to have an
empty frame between the sound sprites. Sort of giving
Director time to
take a breath before starting the next sound. Or you might
try using Lingo
to play the sounds instead.
If they're not already, make sure the sounds are all sampled
at the same
rate and bit depth. This may be needed even if using Lingo to
play the
sounds.
