I just bought a new speaker system and I'm not sure how to connect it to my PC. The system is not brand new, and the inputs are RCA. Can I just get an RCA to something cable? The something being my next question, Which output should I use on the computer? I have one spare VGA connection on the back (I already have 3 monitors) so could I get a VGA to RCA and just connect the audio cables? But then would the computer try and recognise that as another monitor? I'm kinda lost here.....
