hooking up a receiver to a comp
So, heres what i'm thinking. I recently upgraded my home theater system's sound, and have two decent tower speakers left over with a decent yamaha receiver. So, ideally, what i would like to do is hook up those two tower speakers to my receiver, as well as my comps current 5.1 system. Now my question: one, since my computer speakers have cables that plug into the sub, could i strip off the connectors and hook up the speakers to my receiver? 2nd, newer motherboards, specifically the asus p5k deluxe which i am getting for my new comp, comes with an optical Jack built in. Now, i want the best quality for my sound system as i listen to a lot of music, should i be looking into adding a sound card to my build or will the onboard sound be suffient? If not, what would be a good sound card?
