How to connect my Dell XPS 8900 to my 5.1 receiver

[roguewarrior]

Hello,

I just got an XPS 8900 - which sadly does NOT have a S/PDIF connector on it. What it does have is:

Realtek ALC3861 7.1 integrated audio
Gray = Middle surround out
Black = Rear surround out
Orange = Subwoofer and center out
Pink = Microphone
Green = Stereo out, Front Speakers, Headphones
Blue = Stereo Line in

You can see more here at the SPEC PDF: http/downloads.dell.com/manuals/all-products/esuprt_desktop/esuprt_xps_desktop/xps-8900-desktop_reference%20guide_en-us.pdf

My receiver does not support HDMI (it is old school sorry) - just component video and audio. Anyway, my question is - I can either buy an Asus audio card to get back my SPDIF connection or I can connect the receiver using the cables.

First question is - for 5.1 Surround sound which of the 6 do I use? Also, if I use these connectors and not S/PDIF as I have been using for sometime now, on my older computer - will I still be getting Dolby-DTS and all the other goodies I have been getting with my SPDIF connections?

Thanks!

you may want to show us a photo of the rear of your receiver (or just google your model number and link to an image of yours)

component video only includes a red+white cable for audio (2.0) if i recall.

spdif optical can be 2.0 or 5.1 depending on support of both devices. see if your optical jack on your receiver supports surround sound with DTS or similar.
