Hello all, This is my first time posting here. And I wanted to know if anybody knows how to solve my problem. I have a Quicksilver G4 800 and anytime I unplug my external speakers or if I plug in a pair of headphones I get all sorts of noise. When there is nothing plugged in, the internal speaker makes a crackling and popping noise. If I plug a pair of headphones into the back I get a loud buzzing/humming noise. If anybody has any advice I would greatly appreciate it. Thank you!!
