PlaybackLoudness value not replicated between server and client?

I will explain; I am trying to make a quick audio visualiser. But I have stumbled into this problem where only the client will update the value "PlaybackLoudness" inside of the sound (I have made sure the server plays the audio at the same time, I am running this mostly server-side). I have checked and I am constantly updating the value of it (etc...). But I cannot seem to figure out how to fix it after about half an hour so I am asking for help here. I must feel free to mention that help is appreciated; but straight answers aren't for me, I like to learn by experience and not being directly told. Sorry if I am picky, just someone who likes to learn through their own experiences but this one has really struck me. otherwise; Thank you!

Apologies for my hard-to-read writing.
