so my set up is a pair of polk series II bookshelfs speakers and a center speaker. I have a denon avr 1612 with 16 awg oxy-free copper wires.Never hooked up speakers before so not sure if it is completely right. I have static every now and then at certain pitches when the speaker volume is barely even high. Also the center speaker doesn't play even though the avr recognizes it and the computer does. I also use hdmi cords from laptop to avr to TV.
