I really hope that this is just a stupidly easy problem that I can't fix, but I can't get my microphone to work. When I go to the Control Panel to test the hardware (as has been suggested to me), I get the following error messages:
"An error occurred during DirectPlay Voice setup. The error code is 0x80004005."
"Windows cannot execute DpvSetup.exe, use Add/Remove Programs control panel to install."
Try the registry edits there and also reinstall the latest DirectX.
Done. Still not working. Additionally, I can't get the registry edits to stick. I change the values, and I close the registry, and I open the registry to make sure the values are still there, and they're not.
To the contrary, I remember eons (months?) ago when they used to have a blue "Cached" link almost exactly where this green arrow is now so it was much easier to look at the cache then than navigating the hoops and hurdles (ok, extra click)
