Alright, so I just set up the Harman/Kardon Sound Sticks and plugged them into the line out/headphone port. I crank the volume on iTunes and the computer all the way and I get a normal listening volume. It's not even close to loud although it's not quiet either. How can I make the computer put out a higher volume output? Whats wrong thats making it not go louder? Any ideas? Thanks in advance!
