Kewl. Glad sound card works
As for the mic, it shouldn't need any drivers.
Plug it into the microphone port, and then that should be it. Check in the Sound Volumes that its not muted, and try going into Advanced, and possibly turning a MIC Boost on.
Other issues if it isn't working, could be that its not set to record from the right device.
To fix this or to check, open the Volume Control, and go to Options, Advanced Controls (Will allow you possibly to turn on a mic boost), and then go to Options, Properties.
Select recording and list everything. Press okay.
Click microphone as the recording device by ticking underneath it.
Now go back to the Properties, and select Playback again, and again make sure everythings selected, or at least the microphone is to display, and check settings, turning up and going to advanced to check for that boost that may help alot.
I hope this helps.
