I know this is slightly off topic, but I can't post in Not BF2s, Not BF2 and thought people should be warned of this possible pitfall:

If u run a GigaByte GA-7N400Pro2 based PC, DO NOT install nVidia Audio Drivers v4.62 - You'll lose the use of any analogue (i.e. not usb) microphone!

This issue may apply to any nForce2 based system. It may only apply to my GA7N400Pro2. Your mileage may vary.
