Getting sound from the 360 when using a comp monitor?

Thinking about getting a 360 soon and hooking it up to my lcd monitor. What kind of adapter would I need to plug into my sound card so I can get sound from the 360 using my comp speakers?

Stereo RCA female to stereo eighth inch male "headphone style" connector.

It looks like this:

Cool, thanks!

It would help if you listed your sound card and speaker setup.

If your sound card (or speaker setup) has an Optical In, then just use that for dolby digital 5.1. There is an optical out on the Xbox360 VGA connector (it's not on the console itself).

Other than that, get a stereo RCA (female) to stereo 1/8 inch (male). Plug that into your "line in" and set your software to play the line-in source. 2 channels of awesomeness. Edit: Bah, someone beat me to it, with a picture too!
