WEll, last night I went to plug my headphones into the front audio jack on my Antec 900, and no sound came from them, it was still coming from my normal desktop speakers. I have a Gigabyte GA-P35-DS3R mobo, Antec 900 case, and Win XP, and I connected the HD audio, rather than the AC'97 cable, to the F_AUDIO whilst building. Does the HD audio not support the front panel, whereas the AC'97 does? THanks for the help, I appreciate it.
