[PD] Turn off Output~ automatically

[narbino at ucsd.edu]

I have multiple output~ in a patch that have 2 number boxes feeding to it,
and when the numbers are moving the output~ turns on but when the numbers
are not moving it continues to play the last sound played. How do i turn
off the sound when the numbers are not moving without having to mute it
myself?? Thank you.
