Is there a way to stop a looping sound?

No, but it allows you to make sure the correct reference is captured by checking if your item has been removed.

From what I can see, your sounds are named sound1 with same file name + .ogg / .snt etc.
Humor me and try what I suggested. It may not do anything, but I don't really have any other suggestions right now.

If it doesn't help, perhaps package it all up and send it over and I can take a look.
