I'm in a bit of a dilemma over what to get for a 5.1 setup. I have a sound card with optical in/out as well as the analog 5.1 connections. I've never set up a 5.1, but I was wondering if I could connect an analog 5.1 set to my sound card and have the consoles connect via optical in on my card to output the sound over 5.1 analog? Is this possible, or would I need a home cinema system to do this? And which 5.1 set would be ideal (would these work ok and have a decent sound, or should I go for something better)? I mainly want to go 5.1 for audio positioning in games, as I use my headphones less and less nowadays and my stereo speaker setup just isn't ideal anymore. Any other suggestions are welcome.
