Figuring out how to access sound files? Want to remove chattering following the player..

[NoMediocrityAllowed]

Hey,

 

So I hear chattering following me absolutely everywhere, even when I'm with a single NPC, or outside in the middle of nowhere. I would like to just unpack some files, delete or dummy up the chattering sound and repack it all easy peasy. My immersion is broken so often it just makes me wanna stay inside Hogwarts just so the chatterings are justified.

 

What is the engine used (I believe Unreal)? Is there any packing unpacking tools that I can used already to data mine a bit? I see utoc, ucas, pak files that could have what I want.
