Recently, I purchased a 2.1 amplifier and I'm a bit confused by its audio input. It features a 5-pin connector, yet my audio setup only has three components ground, right, and left. I've successfully connected the ground to the '0' on the board, but I'm unsure about which pins correspond to the left and right channels among the five.
