Q: Bootcamp XP SP3, Built-In Mic Not Working

Hello,

I recently purchased a copy of Snow Leopard and so updated my Boot Camp installation from version 2.something to version 3.1. Since this update, my internal microphone has not functioned properly. It is not completely dead; rather, it appears to play back any voice recordings choppily and sped up, so that the changes in pitch render the voice communication unrecognizable.

The odd thing is that if I use the built-in "Sound Recorder" application in Accessories/Entertainment, it records fine, but if I perform the microphone test in Control Panel/Sound and Audio Devices, or attempt to use the microphone for communication in online gaming, it sounds as described above. When I updated Boot Camp, I noticed a new control panel called IDT Audio, so I suspect these new drivers are responsible for the issue, but I have no idea how to troubleshoot this issue. Any thoughts?

I have an old MacBook Pro (Core 2 Duo @ 2.53Ghz) and 4GB of memory. I am running OS X 10.6.2 (in which the microphone works fine!) and Windows XP SP3 with Boot Camp 3.1.

please help me to solve this issue , My audio driver is Circus Logic High define nation audio ..

advance thanks to all
