Onboard Sound No longer works

I just upgraded my old case to an Azza Solano 1000 (http://www.newegg.com/Product/Product.aspx?Item=N82E16811517004&Tpk=AZZA%20Solano%201000). Everything works fine with the exception of audio. After switching my Motherboard, and other components over, I plugged the Power and Reset buttons, along with the associated LEDS and the USB ports with relative ease. When I booted up I had no sound. I am using an SPDIF output, which worked previously, but does not register anymore, along with the audio jacks on the front panel and the on board sound. I have reinstalled my drivers, and checked my motherboards manual (or at least as close as I can get) from the HP site (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01077676&lc=en&dlc=en&cc=ca&product=3548643&lang=en) to no avail. I know I have everything placed correctly, as the front panel for the previous case plugged to the same spot. The audio cable for the front panel has 2 plug on it, one which read "HD audio" and on reading "AC'97" Each adapter has 9 pins, but the motherboard has an area labeled "HD Audio" with 15 pins and one with 9 pins which I have tried with no success.

Any Ideas?

Yea, all the limited BIOS gives me is the "Audio Codec" option, and I've set it to enable, auto and disable at least once and it didn't do a thing.
