[Question] Changing sound files

I was searching for a way to change the sound files for Battlefield 4, yet I could not find anything conclusive. This is why I have come here, does anybody have any idea how to do so?

I apologize if the flair is frowned upon, but I’m really desperate to replace the 870 firing with a goat sound.

Why? Just…why

Why would you not want it to make a goat sound?

Id rather give it some more bass. Two different people here.
