Well, I am using 5.1 EX setup...and it can't be much better than mine. The audio quality during the film varies substantially depending on the channel being used, but for the most part it seems like a complete fuck up. For instance, you can hear Han talking to Leia on the Falcon and it'll sound crystal clear (incredible quality) and then it'll sound all muffled and like it's coming from an old ass record player or something. I had to listen to it off the tv it was so distracting. However, the other films sound fine.
