Coaxial, S/PDIF out to stereo

[mystvearn]

Do I need special coaxial cable, or any coaxial cable?
Coaxial is the cable that looks like the PS2 cables to the tv right?
This motherboard supports the S/PDIF out, but there is only one socket. What does that mean?
I want to hook it to my stereo system, to get the surround sound. The stereo has two slots for the AUX, L & R(left & right). I need this cable which has two out right?

Here is what I'm doing. The options for the stereo system does not allow 4.1, using the coaxial, the application gives me another option-using a another socket(which looks like the pc speaker) for the rear channels. But when I connect it to my stereo, I hear a fizz sound when I crank the volume.
The other thing the speakers do not respond well. The left channel(rear) is not working. The right channel is working but on both speakers.
The wire, I place into the mic slot, since I don't have a split jack to L & R.
Is there a problem with the cable because I hear the fizz sound?
And the Left rear is not working properly.
Hope I made it simple.
Stereo System: Panasonic SA-PM11

Thanks

your reciever needs the same spdif connection. and for some reason most recievers dont have this. most will have the opictal digital hookup.

I have both optical & S/PDIF. I have manage to solve the problem, went out and bought a splitter cable. No more fizz sound. And both channels are working

[Hi Ho]

If it is working then there is no problem. I am just curious and confused. There are two digital connections. Coaxial and Optical. They are both S/PDIF. Both carry all channels through a single cable digitally. If you are using a coaxial connection then you need 75 OHM coaxial cable. Otherwise it won't work right. You say you used a splitter? I'm guessing you are just using an analog connection?

I'm confused as well. A coax audio signal wouldn't need a splitter - it carries all channels of audio data on one 75 ohm cable. Same with optical (toslink) - all audio data is carried via one lightpipe or optical fiber cable.

Splitter, from the normal speaker jack. It looks like the jacks on walkman, the small jack, usually indicated by green color rim
I bought a cable from that jack to a RCA slpitter, L & R

[Hi Ho]

OK, I was just confused because I thought you were using the digital connection. Anyway, you would get better sound using a digital connection. If you want to you can buy 75OHM cable or a Toslink optical cable. I prefer Toslink but they both sound the same. A cheap way to get 75OHM cable is to buy an F-Type cable (same thing used for cable TV) and use a couple adapters like THIS. That's how I solved my humming subwoofer problem in my home theater system. At $6 for a 15ft cable it's much cheaper than buying a $40 12ft "subwoofer" cable that is basicly the same thing.

I have one connection like that at the rear of the pc. So that is the S/PDIF connector? I notice the screw lines, so I can plug that to RCA?. Now I hear the sound as the same quality.
For some reason i can only use opticaL/ S/PDIF of I'm using 2 channels. I adjusted 4 channels, it would not allow me to. The software game me other jacks to set up the system.

[Hi Ho]

That single RCA jack is the S/PDIF output. That would be hooked up via 75OHM cable to the coax digital input on the reciever. It sounds like you are using onboard sound. Unfortunatly, many onboard sound chips only offer two channel digital out. Mine does and it sounds like yours does as well.

[mystvearn]

Yes, I have onboard sound. C-media sound card. It supports up to 6 speakers. What I did was the only option then
