Audio Buzzing?

[RiversideGuy]

For some reason, in the past week or two I seemed to have acquired a constant kind of buzz from my speaker. I can hear it best if I mute the game audio... then I can hear it plainly. If a switch to the windows desktop, it kinda changes, but is still there. If I QUIT the game entirely, bingo, silent as a rock. Tried playing some music, sounded fine, when the music was shut off, speaker got silent (as it should).

Somehow I have this memory that I've seen this before... but I can't for the life of me figure out how I solved it. Sure hope one of you'all had this issue and solved it... could use the help.

Oh, It may very well have been with the launch of 7.1.5...
