Is there a way for my PC to output 5.1 surround sound through its headphone jack by connecting it through a male to male 3.5 cable to the auxiliary port of a DVD home theater (LG 355-SD) setup? Will that give me 6 separate channels?

The ht system has no HDMI and optical in. Is it better if I use a male 3.5 to rca cable. Will that give me 6 separate channels?

Sorry mods if I placed this in the wrong thread. Don't know where else to put it and I'm assuming that the audiophiles here would know the answer.
