Hi guys, i know there is alot of this related stuff on google but i'm very confused...

What i have:
*LG DA-3530 Home theatre CD/DVD system, about 5 years old. DVD laser, or spindle motor is defective, not going to bother getting it repaired (have a Samsung R135 now). So now i got this thing sitting in storage doing nothing (and I'd like to get rid of my X-230 speakers).
*Dfi NF4 board with karajan audio. (yes i know most purists would say i need to get rid of onboard, but i'd rather test it out on this first)

What i want to do:
Connect the 6 channel system to the PC. The speakers/sub use to be on a simple wire with negative and positive leads. A while ago, i soldered RCA jacks to them.

As far as i can see all i need for analog, is 2 RCA Y'd to a single stereo mini jack (3 of these to connect Front left/right + Rear left/right + centre/subwoofer). But how would volume control/amplification work? How can I use the DVD player as a receiver/amplifier??? This is what really confuses me as every guide out there uses a volume controller or receiver and I really don't have the money for a $300 addition.

Well you need to have an available input on the LG system that can accept 5.1 analog(doubtful) or SPDIF. If you only have a "stereo" input you would be stuck with only two channels of audio, via a L and R RCA input. The best bet would be to go from SPDIF output of the mobo to SPDIF input of the LG system, which is a receiver/dvd combo yes? The volume control in Windows or on the LG combo system would be work simultaneously. Choose one volume to set permanantly and adjust with the other, whichever is more convenient.

I cannot see a SPDIF in on the LG.
I"ll list the rear panel sockets:

FM/AM radio
Auto-ntsc-pal switch


woofer out (rca)
S video out,
Monitor Out

Video2 IN (L, R, Video)
Video 1 Out (L, R, Video)
Video 1 In (L,R, Video)


front Speaker R/L using simple +/- leads)
Rear Speaker R/L
Woofer
Center R/L

It also says on the back label "CD/DVD Receiver" but definately looks like it does not have SPDIF input. Looks like I've hit a brick wall?

u dont have digital in on LG sooo....
send stereo signal from pc's front audio output (on Karajan) using headphone type socket....... to LG left & right RCA Input 1.
LG will be providing your surround sound and ur peak volume level, whilst u adjust using pc volume output.
from my own experience...pc onboard sound aint that special when run through hi-fi separates.
