Let me enjoy the ranks.....got it since today. All I did change was disabling the Aero Interface.
When moving the mouse, the crackling sound appears. All games installed are effected, once moving the mouse.
Other media played (whether using KMP / Nero player or WMP) works only when the mouse is not moved. When moved the cracking sound appears, once you stop the mouse, the cracking sound stops.
Looks as if there's an interferance between the mouse and sound.
Cheers,
Hank
