I'll try to include everything I know.

System specs:

OCZ PowerStream 520W
DFI LanParty UT nF4 SLI-D
2GB OCZ PC3200 (1GBx2)
Nvidia 7800GT
Creative X-FI ExtermMusic
Netgear GA311 Gig nic
Logitech MX1000
Logitech Quickcam Fusion
3 SATA HD, one ATA DVD burner
Windows XP SP2

I have downloaded and install all XP updates, I am using the lastest drivers for my motherboard, video card, sound card, webcam, mouse and so on. I have tried doing a fresh install of XP and along with trying differnet USB ports to resolve this problem with no luck.

The problem:

As soon as I plug in the webcam, audio hardware acceleration gets forced to basic acceleration. This casues hardware mixing and the use of a hardware buffers to be disabled in windows. If I run a game like FEAR, hardware mixing will be greyed out, running dxdiag's sound test will bring back an error saying my sound card doesn't support hardware buffering, Under the properties for Winamp's directsound output plugin it will say hardware mixing is unsupport and during playback uses a software buffer.

If I unplug the webcam and go into control Panel->Sounds and Audio devices->Adv tab under speaker seetings->under performance and reset the acceleration back to full I will have full hardware support again in most cases. There are times when I must rest my computer. When I don't have to restart my computer all I have to do is plug the webcam back in to restart the whole problem again.

I have also just noticed something else today in device manager. There is a entry for the webcam's microphone, if I go into its properties and disable its audio device which is listed as USB audio device it ends up disabling all audio devices.

Does anyone have a clue what the problem might me? Does anyone even understand what I'm trying to say?
