How do I fix an issue where sound replicates itself when...

When a player gets a certain amount of points in my game, the game creates and object at a certain part of the screen and the object doesn't move, but there are objects in the game still moving. There is a sound that plays at the exact same time when the player gets a certain amount of points, and for some reason, this makes the object multiple a few times. How do I fix this?

A blind guess, since we have no idea how you're doing all this (a capx would certainly help):

add a "trigger once while true" to whatever is triggering more than once that you don't want to.
