Alright guys, I have come to the conclusion that this problem can only be a result of a faulty/old motherboard. Any insight/confirmation/insults are appreciated. Problem: My speakers have been crackling on a consistent basis for the last month or two. Sometimes they are quiet for a half hour at a time, but other times they crackle constantly for several minutes. This occurs regardless of what programs are running, and crackles at the same volume regardless of the volume of the speakers. Touching the cords does not affect the crackling sound. Things I have tried: I swapped speakers. Three different kinds of speakers are all crackling when plugged in. I thought the microphone might be to blame, but I have unplugged the microphone and the problem persists. I have tried two different sound cards. The cracking continues. ASUS A8N SLI-Deluxe Mobo, approximately 2 years old. Does anyone know what is going on? Thanks.
