Need help hooking up Z560 4.1 speakers.

[algae]

Hi all,
I just inherited a set of Logitech Z-560 4.1 speakers. I'm using the onboard
sound on my A7N8X Deluxe. There is a connector with the speakers that has a
green jack and a black jack combined. I'm not sure where to plug the black one in.
Any advice would be appeciated.
Thanks
Gary

Never mind....figured it out. My TV Tuner plugged into my sound card was throwing me.
