How can I convert a stereo output to surround sound?

My laptop has only a stereo output. Is there any way to convert this to use a surround sound speaker system using any combination of hardware/software? Preferably without getting an external sound card.

for music u cant get SS.
music is recorded in 2 channels L and R.
putting it through a SS system will just make the stereo image wider giving the illusion of surround sound

"Surround Sound from 3.5 mm stereo" is tested and published.

I'm almost completed hardware testing for "Surround Sound from 3.5 mm stereo" Instructables. It is low power version from my "Surround Sound from Stereo" and presents the same quality. Instructable includes detailed schematic, I'll also supply kit.

in addition to Fox sometimes you can change the mic / line in port to work as second line out for the rear speakers if you connect the rear speakers to the amp thru a crossover or invert + and - wires you can make the sound feel more 3D but its not really surround
No. You can probably coax it into playing through most or all of the speakers, depending on the workings of your amplifier/tuner... but it will never be surround sound. This much should be accomplishable with a few basic cables. Getting true surround sound out of a computer requires a sound card that supports it. Some laptops do have it. In those cases it's as simple as plugging in a special cable (that comes with the laptop) into the headphone jack or using an audio-out on the back of the machine. This isn't common though, and I've only bumped into it once or twice.
