Right now I connected HD audio cord to the F_AUDIO pins on my motherboard, the p35-DS3R. The audio cable on the case has a 10 pin connector labled HD audio, a 10 pin connector labled AC97, Currently, I have installed the HD audio drivers from realtek, but there is still no reaction when I plug in the jack. Normally, when I plug in a jack from the back of my case, my computer reacts. Can anyone help?
