I have the sound configuration set to EAX 4.0 and I hear the surround sound just nicely and the quality of sound is a big improvement over the old sound system. I think maybe just the sound distances on a few of the sounds needs to be adjusted but those have really nothing to do with the sound system itself. Also, when the custome sound packs with the sounds tailored for the Miles system things will also improve greatly. I'm happy with these changes, it's been a long time coming.
