Raw audio from old game

Hi!! I use UE sometimes, I am not an expert, I need hear many audios from old game maked in UE, (idk the version of UE) specifically Scooby Doo and The Spooky Swamp(2010), the game has the audios in a separate folder, but i can not play every audio in VLC, I have been reading some of USoundWave but i don’t understand much, the game has .raw audio and when i import this in Audacity there is only white noise, I need replace all audios, is there any way to listen to the audios quickly and replace them with others without altering the game? sorry for my english.

Thx!!
