I have my sony 600w 5.1 dolby/dts reciever set up. It has optical input and digital inputs (RCA). I would like to hook my pc up to this reciever, obviuosly I need a sound card to make this work. I can use the digital or optical input, no preference. (UNDER $20 please). Could use a phono-->RCA adapter on the reciever digital input or not?
