• in windows 7 its near the top in the windows edition category
  
• I will also need to know the service pack

here's mine

You don't need any drivers to make the speakers work what you need is the audio chip drivers for your motherboard ( the model of which you have not mentioned ).At the bottom right hand side of your desktop next to the clock do you see a icon of a speaker ?. If you don't , your sound driver has not been loaded. If you have the motherboard utility disc the drivers will be on it. If you don't ,you can go to the motherboard website on the net and type the model number and download all the drivers necessary to run the PC.
Just remember after loading the drivers remember to restart the PC to make the application run.

To get "surround" sound, when you face the computer, you will have:
* 2 front speakers, one immediately on each side of the computer
* 2 side speakers, one on each side of your head
* 2 rear speakers, one behind each side of your head

Thus, when the sound is of a jet-plane coming towards your face,
you'll first hear the sound in the front speakers,
then in the side speakers,
and finally in the rear speakers,
to produce a sound-effect of the jet passing over your head, and going "behind" you.

Usually, for "front" speakers, one speaker connects to the other speaker, and the second speaker connects to the "FRONT-audio-output" connector on your sound-card.

For side speakers, one speaker will connect to the LEFT-side-audio-output port,
and one speaker will connect to the RIGHT-side-audio-output port.

For rear speakers, one speaker will connect to the LEFT-rear-audio-output port,
and one speaker will connect to the RIGHT-rear-audio-output port.

try right clicking on your volume icon the speaker in your tray the select playback devices and see if its selected or listed if its there and no got a check mark check it and you should be good ..if it isn't there try updating if still no go then the sound card simply wont work for windows

don't forget to give testimonial and the votes 4 thumbs up if I helped.

With the lack of information provided all I can suggest is ..
1. are the speaker wires connected at the radio? 2. are there rear speakers and if so do they work? 3. make sure the fader control isn't set to rear, this would shut your front speakers off

check whether the wire is connected properly on both the ends

I don' know what type of system you have, but try to switch system to "SURROUND" mode, or "DSP" mode.

check that you havn;t mute the speakers in the audio program
start, control panel, sound and audio devices..

Hey Amigo - relax - do you have the Creative sound center installed. There are many options. Do you have it set for 4 speakers? Let me know. If this solves your problem PLEASE rate this as fixed. If not, DO NOT RATE YET. Just add a comment letting me know what's going on and I'll be happy to assist you further. Thanks.
