This is really bumming me out. I've tried all the workarounds people have suggested, but nothing is working for me. Oddly, I have noticed that the sound quality improves if I turn my camera away from the back of my character. It's still bad, but it slightly improves. This got me tinkering with the sound positioning (from camera to character), but that proved useless. This must be related to the new sound features they've added with 6.0. I hope they drop a fix for it by the official release date of EW. Having to sit in queue for hours at a time only to get in and be welcomed by the sound of Decepticons and Transformers having a rave in my speakers... It's a buzzkill before I've even buzzed.
