How do I turn off a specific instance of a sound?

I use this expression to activate and deactivate a fire. It works wonderfully for interacticing with individual instances of a sprite, but not for sound. It properly creates sound at each spite's location, but deactivates all fire sounds when I deactivate any one sprite. How can I select and turn off a specific instance of sound?

I found a solution, but would still like advice if anyone has other methods. Especially as I've heard using IIDs and UIDs is a bad move. I set the sprite's instance variable to be "Self.IID" every tick. Then, when it creates a sound at its own position, I set the tag of the sound to "'Soundname' & object.instance". Then, when the object gets deleted, I delete the sound with that tag. So far so good. I am a little worried it will break as the player places/destroys the objeects making sounds.

IIDs can change so this might not be reliable. It will probably work better if you use UIDs instead.

Basically as long as every sound has a unique tag then you can control them individually.
