A week ago, I installed Windows 7 Ultimate 64-bit on my MacBookPro8,3. I installed all of the drivers Apple provided with the Boot Camp Assistant. I first noticed the my right speaker seemed to sound muffled when I was playing Team Fortress 2, a video game with 3D sound. All the sounds that were coming out of the right speaker sounded muffled. I then went online and played some stereo sounds, and I confirmed the right speaker did sound muffled outside of Team Fortress 2. To make sure this wasn't a physical problem, I booted in Mac OS X and played the same stereo sounds, and the left and right speaker sounded equal and not muffled. Any suggestions? I already uninstalled and reinstalled the drivers, nothing is working.
