Hi I have my PC linked to a Samsung HT 5500 5.1 Surround Sound unit. I have the PC hooked to the TV via HDMI and the Surround Sound hooked to the PC via 3.5mm to RCA splitter but I am not getting the 5.1 surround sound. Its only using two speakers. Now if I used a Optical SPDIF cable from my pc to my surround sound, would that use all 5 speakers and give me 5.1 surround sound?
