Hello all I just got my first Mac Mini and am trying to figure out how to connect my Logitech Z-5500 speakers to it. I'm only familiar with PC's where you plus the green, orange and black 3.5mm plugs into the sounds card. I have an optical cable and i'm sure an optical to 3.5mm adapter would work? I have the optical plugged into my cable box right now so is there another way to get sound? I honestly have no clue how to get sound from this thing, i'm a noob when it comes to audio inputs and outputs. Thanks.
