Have you seen this latency in response times on more than one computer? If so, could you please send us a dxdiag.txt file for each machine? You can create it by clicking on the Start button, typing dxdiag in the Search box, and then running the dixdiag.exe application. This will let us take a look at the sound hardware and software that you are using.
Also, is there a way that you could connect the microphone directly to the sound card, maybe a port on the back of the computer? This would be a good test to see if the connection port you use on the front of the computer is part of the observed reaction times.
