I have a dolby digital 5.1 sound reciever. I figured out that if I use a red/white to single 3.5 mm adapter, plug the red/white into my receiver and the 3.5 mm into my headphone jack on my computer, I get complete 5.1 surround. Has anyone ever tried this?
I get 5.1 surround sound through one 3.5 mm port

It's not real surround. A 3.5mm stereo plug only carries ground, left, and right signals.

Not to be rude, but, I don't believe you. Headphones can fool you into thinking stereo sound is surround pretty easily as well, simply because the sound engines in games are very good at tricking your ears. It will reduce certain frequencies of the sound, just like it would in real life, so that it sounds like it is coming from behind you, just like in real life.
It is physically impossible for a standard 3.5mm jack to transmit more that two audio signals. It is also physically impossible for a receiver to know what sounds belong to what channel, and reroute them accordingly.

I have a Newer Yamaha Receiver and it will do something called Matrixed Surround. It takes sound from the two Stereo Channels and adds delay and reduces the gain so it sounds like the sounds are echoing off a back wall which gives you this effect.
Think about it.
Composite cables only carry two channels. Left and right. There is no way for it to know where to put the sound except from right to left. There is probably a logic setup so that when only one side is supposed to play the sound it ups the gain on the rear speaker of that side.
SO yes you are getting Surround but it's matrixed surround from your receiver.
FWIW I think matrixed surround sounds pretty darn good for not being 6-8 discreet channels.

No one in this thread has heard of pro logic before ?....
Yes he is getting virtual surround sound....
He is most likely using pro logic II which decodes a stereo source, and trys to place voices in the front, and effects to the rears.
It sounds like crap compaired to true surround sound, but yes this is possible.
Please research before you bash someone.
Although once you go to digital dolby or dts surround sound, pro logic is crap, since it distorts sound.

He was talking specifically about the difference from an exploding grenade in front of vs. behind him. Unless pro logic somehow detects an exploding grenade out in front as a "voice", and an exploding grenade behind as an "effect", I don't see how it could make a difference.
