Not sure if this goes in here or in video cards, so let me know! I have a spare Pioneer 5.1 receiver, with HDMI in. I'd like to use it for surround sound with my gaming PC, but I use DVI for my 4 monitors. Can I use one of the spare HDMI outs (Like from my 650 Ti) just as a sound card? I.E. there's no monitor hooked up to it, just audio. Thanks folks!
