5.1 channel sound problem

i am using an Aspire 5720G with a Realtek High Definition Audio card.with a driver release 1.96 ,this system is runnig on a preinstalled Vista home preimum os.now i want to run a creative sbs 580 (5.1 channel) sound system but it is giving me option of 2 channel system only and only front speakers are giving sounds. please help me to configure it for 5.1 channel sound.

 

are you using optical ?
if you have no SPDIF ?
i have the same card in my laptop and it goes all the way to 7-1
just looked at your spec and you have optical.

you will need a mini tosslink adapter
which go's in the headphone jack(see pic).

If you're willing to put up with three analog cables, you can actually set up your Aspire's sound card to output 5.1 sound using the headphone, mic, and line in jacks. I forget which is which, but each jack outputs two channels when set up like that - Center/Subwoofer, Front Left/Right, and Rear Left/Right.

 

i used the realtek control panel and found optical had better sample rate, less interference from power source's

 

thank u guys for a quick reply, but my sbs 580 is having three analog cables only and it is not having any optical interface. therefore i would rather want to use these cables.hence if there is any way to turn three audio jacks to output audio interface as sugessted by TehSuigi. Can u elaborate the while configuration

 

on the spec sheet you have optical. is the problem lack of optical on your amp ?

 

ya , u r right .I don't have optical interface on the amp, thats why i a want to use audio jacks. B'coz here in Saudi Arabia it is difficult to get an optical interface sbs 580.
Hence if u can suggest some way to use available resourses in Vista.

 

ok will try and find you an answer mate
