Works in Test AND in Server, but not in actual game?

I know I know, I'm not supposed to post a "how to" question, however I'm really confused. I'm making a horror game, and its very auditory. The audio parts work in test AND in a server (that I start in edit mode), however when I actually play the game from the website, the audio doesn't play.

This really confuses me because I thought starting a server in edit mode was treated the same way as playing the game from the website. Any reasons of what causes this and how to fix it?

Playing in Edit mode is not the same thing as playing on a server. When you play on edit mode, both localscripts and regular Scripts are run on the client. You are running into a problem because you are doing something you should be doing in a different kind of script.
