Yeah, definitely plugged into the right port, but they are headphones... Doubt that makes a difference, but no speakers yet. The Realtek HD Audio Manager program recognizes that there is something plugged into the green audio port, but Should the sound from the Video cards HDMI work independently or does that also depend on the onboard chipset for it's output? Some people have complained about the case I have having some bad front ports, and the audio is connected to the MoBo, but not in use ATM, could that be causing a conflict, maybe? Also, there is no guarantee that the onboard sound is working, though I do hope that is not the case. If you figure anything out, let me know, in the meantime, I may start looking at sound cards... *sigh*
