Can't use microphone in XP mode

[chillers]

After opening XP Mode, can attach the microphone with the USB tab at the top, but it doesn't see the microphone in Control Panel, and so doesn't work. I had it working for another user, a while back, by changing some audio setting in a file from True to False, or the other way around, but can't remember what file. Does anybody have any idea? It's a Logitech AK5370 Microphone, if that helps. Thanks!

If anyone has the same problem, this is what I found to fix the problem.
1. Go to C:\Users\%username%\AppData\Local\Microsoft\Windows Virtual PC\Virtual Machines in the Windows 7 OS
2. Right click Windows XP Mode.vmc and open with Notepad
3. Find <ui_options>
Change <audio_redirect type="boolean">true</audio_redirect>
To <audio_redirect type="boolean">false</audio_redirect>
