At some point is paused ticked is going to equal 0 and you're not providing for that.
So it will add 1 while it is negative and then stop at zero. Your next step is to test it when it equals 1 and I don't see where it's going to go from 0 to 1 (unless that's just not part of your screenshot).
From my understanding - the code that you have written will cause Fusion to play a sound once every frame loop. From what you're explaining you don't want Fusion to do that - but that's more or less what you've programmed.
If you want the sound to trigger on an action then you can change it to:
Set Sound = 1
If sound = 1
Set sound = 0
