I have a sharkoon xtatic 5.1 analogue headset and for some weird reason the mic just doesn't seem to work on my current rig. I'm have an Asus p7p55d mobo with a Xonar DG soundcard and I'm running windows 7 professional 64 bit. The mic doesn't work with the soundcard so removed it and unistalled the drivers, and tried again using the onboard sound and for some weird reason the mic does not work with the onboard sound either. And the mic itself is not faulty because I plugged the mic in my hp laptop and it worked flawlessly. Does anyone have any ideas? Thanks.
