How to connect home theatre 5.1 ch to pc ?

[ledu00]

So I have Samsung HT-THX25 and It's broken but it's audio works perfectly fine so I'm using it as my 5.1 ch audio for pc. No connection to tv. So now I want to know how to connect it to pc and for PC to see and use it as 5.1 ch surround ? This way center speaker plays all the sounds, sub plays the bass and other 4 speakers play extremly quiet sound. In Realtek Audio setting all test sounds are played from center speaker. What should I do to make it work ?

P.S. It doesn't have HDMI in.

di you try to use the way they show on page 20 beside hdmi settings to plug output from computer to aux in on the receiver or use the front usb may like the one with a mp3 player .

Aux in is the one I'm using now and how do I connect it via usb ?

on the user manual they show that you connect usb from front panel on receiver like they does with mp3 .
