Sp/dif

Sorry if your sick of hearing about this, I have searched the forum and read everything there is to read. My question is this:

I have SP/DIF out on my Toshiba laptop which shares its output with the headphone jack. Drivers allow you to swap between digital out and headphone out. My Creative DTT3500's have coaxial digital input. I went out and bought a IXOS 75ohm digital cable (as I am aware SP/DIF requires a 75ohm cable) and a rca -> 3.5mm mono minijack adaptor. Connected it all up and viola... no sound. After reading the various posts on this topic, if I had to use a simple audio patch cable (stereo minijack -> 2 rca) would one of the rca plugs carry the digital signal? Does the cable then not have to be 75ohm? Someone said I needed a 3.5mm stero minijack adaptor, but since the coax cable is a single core it only carries one signal, correct? Any help with this would be greatly appreciative! After spending £50 on the cabling, I wanna get this working! Thanks again for any help.

PS. I know I dont have a sager laptop, but everyone here is just so helpful I thought I would make a post.

i do a lot of audio stuff, so i think i might be able to help. if the input on your receiver is stereo, you are going to want to get a stereo minijack. if the coax cable has two inputs and two outputs on either end, it is stereo regardless of how the cable is wrapped. i dunno anything about the impedance business - i wasnt aware that SP/DIF had to be at 75ohm. is that a digi cable you bought?

Yea its a digital audio/video 75ohm single rca -> single rca cable. The rca coax input on my reciever is just a single female plug (right next to the optical input which is being used by my PS2) After trying to research on the net, I found that SP/DIF cable has to have a nominal impedance of 75ohm. After reading a lot of posts about SP/DIF, im beginning to question this.
