HDMI onboard sound

[detras]

My motherboard blew up and I replaced it with the xfx nforce 630i/7100 GeForce. It comes with HDMI audio. I don't use the surround sounds as I use my computer for gaming. I wear a headset with microphone so I can hear and chat without disturbing the other members of my house. The headset has an USB adapter or can use the standard pins for speakers and mic. How do I go about configuring my computer so that I may use my headset and get around the HDMI capabilities. I want to utilize the sound capabilities that are onboard but not with the HDMI ports.

Not sure what your problem is? The headset just plugs in the pink and green jack sockets on the rear?
Are they not there?

i thought that headphones with usb ports as a rule have their own "soundcard" on the usb dongle and so wouldnt use the onboard sound at all...
