How do I get surround sound with these speakers?

I am planning to buy these but my laptop only has an audio jack and a S/PDIF jack they are both 3.5mm jacks. http://www.newegg.ca/Product/Produc...o6b0tCA-_-Speakers-_-Logitech+Inc.-_-36121120 How would I hook it up so that I can get surround sound because the pictures show like 4 different inputs on the speakers.

 

isnt spdif the same as optical?

"All you need is an optical SPDIF cable that looks like this. Note the miniJack/Toslink connector"-D3X

 

Thanks, I didn't know that S/PDIF out was optical and thought you can plug in your regular 3.5mm plug speakers into it.
Do you think I might have damaged the S/PDIF out port? Or is the S/PDIF plug is the same as the 3.5mm audio plugs?

 

S/PDIF doesn't have to be optical. The digital signal can be transmitted by coax cable also.

I don't know your laptop, but chances are the S/PDIF signal those speakers you mentioned accept is via non-optical methods.

 

optical or S/PDIF is essentially the same, but as stated as above s/pdif can also be coaxial. I use a z-5500 to with optical but it also has an digital coaxial connection (looks like RCA but it is only one) or the 6 ch direct connection which is 3 x 3,5mm jack.
