Right speaker problems on Windows 7 running on a Macbook Pro

a week ago, installed windows 7 ultimate 64-bit on macbookpro8,3. installed of drivers apple provided boot camp assistant.

first noticed right speaker seemed sound muffled when playing team fortress 2, video game 3d sound. sounds coming out of right speaker sounded muffled.

went online , played stereo sounds, , confirmed right speaker did sound muffled outside of team fortress 2. make sure wasn't physical problem, booted in mac os x , played same stereo sounds, , left , right speaker sounded equal , not muffled.

suggestions? uninstalled , reinstalled drivers, nothing working.

 

i have noticed same problem recently. have figure out way fix it? post solution if ever got solved.

update:

updated driver using windows automatically search online. installed new driver , problem not bad used still right speaker still sounds lower left.
