Awesome that is the right-part number but nowhere do-they speak about the chipset. OK the black audio connector block that you connecting to your board what does it say on that small block that you are connecting either (HD AUDIO) or (AC 97) it will be written in white font on the black connector piece. Otherwise what motherboard do you have? is it a Gigabyte, if so you can configure the output audio ports to either HD Audio or AC97, take a look at that as well all more recent boards boards should give you that option.
