Community help,configurations and settings

S! Gentlemen. Can someone here help me reverse CoD's left/right sounds for a Plantronics USB headset? I've tried conf.ini "Soundflags.reversestereo=[settings 0 - 2]" and no change. Can't find a setting for this in the audio menu and have Googled this subject to death, searched all CoD forums and read all six pages of this thread. There's some good stuff in here for later reference BTW

Other than this little problem, the game is running ok for a beta on my Win 7 rig.
