I just purchased the Dual 2.5 Ghz G5 and I am having problems plugging my Logitech headset into the ports. I can hear the audio, but the connection for the mic doesn't seem to be making proper contact. When I plug it in, I can see the levels spike for a split second in my audio control panel, and it feels snug, but something isn't lining up. Has anyone ever had this problem or have any idea what the solution may be?
