Do ambient sounds not work?

In a map I am currently making, I want to have rain playing in ambiently in the background. I have the sound and the script in the workspace. When I run or play solo, it doesn't work. The storm script I have, which makes the lighting change and the thunder sound boom, does what it's supposed to do.

Here's the script: script.parent.Rain:Play()

I've looked it up in several other questions, but none have told me why. At this point I'm completely lost as to why it isn't working.
