How do I connect my Xbox 360 to my PC speakers?
For surround sound you will need to purchase an optical audio cable and plug them directly into your surround sound speakers, if your surround sound speaker don't have an optical or coax audio port, you cannot use those speakers for surround sound and will need to buy new speakers. If they have a digital coax port you will need to buy an "optical to coax converter". If you don't have surround sound speakers or simply want to use analog audio you will only need a 3.5mm stereo female to two RCA Female.
