Hey, I currently have the Altec Lansing VS3121, and I have both my Xbox 360 and PC connected to it, and can play both audio inputs at once without the need to swap wires. My Xbox 360 connects to the speakers via the RCA (red and white audio) cable that is attached to the Xbox 360 VGA cable, my speakers connect to the 360 via 3.5mm lead that goes into my sound card. I'm looking for either 2.1 or 5.1 speakers, under £50 that I can connect my 360 and PC to, with the same sort of setup as above. I would greatly appreciate any responses that lead me to a purchase. Thank you!
