Preload not working/not loading sound id's. Help?

I have this problem where my sounds did not play in game but in studio. So i searched the wiki and apparently there is a feature to preload.

I tried:

:Preload(ASSET ID) --To sounds

and also

PreloadAsync({game.StarterPack:WaitForChild("Intermission"),game.Workspace:WaitForChild("Bus"):WaitForChild("StartTheBus").Script.BusIdle)}

And none worked. No errors, nothing in the output. How do I fix this? Without sounds the game is just bad.
