I've had this issue for a while now and I'm finally fed up with dealing with it. The problem is, when it's raining and I go into a building (inn, house, Dragonreach, etc.) the rain plays indoors. It plays very loudly and like I'm standing outside in it when I'm obviously not. And it's weird when it plays like it's suppose to (muffled and sounding like it's hitting the roof) one time, and then the next it's destroying my ears and playing the wrong sound. I'm fairly certain it's a mod, but I don't know which one. For weather, I use Pure Weather, and I use Real Shelter if that happens to contribute to this issue. Other than that, I don't know what to do about this.
