Hey sorry for the late reply, I honestly can't implement that, would love to. I'm modding on Linux and the sound engine of the game uses proprietary parts why it would be hard to do. Why on the mod page and comment section I've been promoting other mods that add such functionality I cannot, like custom looks or Yahweh as a God. I encourage you to make a sub-mod if you have the know-how and there are guides how to do this sort of stuff for Warhammer.

Here's a Guide:

For me the issue is Wwise. But this isn't the easiest part to mod tbh, but I'd love authentic sounds. :)
