ok so Ive had the 15" mbp for a week and a half but now im starting to think that the left speaker making that static issue is a hardware issue. I dont remember the 17" mbp making that noise and not sure if the 17" mbp had the high pitch noise using external speakers and I have a nice stereo system with b&w speakers and the 15" mbp making the high pitch noise in the background is starting to bug me. My question is does the 17" mbp make that sizzling weird noise on either of the speakers after any sound has played and does the 17" mbp also have that high pitch problem via headphone jack as well. I have a micro usb sound card by turtle beach but it seems to be too loud even with using it with 1 notch i sound seems to be equivalent or even louder than headphone jack at full sound! If the 17" mbp dont have any of these problems I will go yet another time for an exchange as I use 50% music with my mbp via my b&w speakers/stereo system.
