Intel DP965LT and Microphone

Not that long ago I got myself a new system based on the Intel DP965LT motherboard. The only thing that I still can’t get going is the microphone. Anyone else have this working with this hardware?

What happens is that basically nothing happens when I plug in the microphone. No output when I yell into it, either plugged into the front audio headers of the case, or the rear. According to the Troubleshooting Audio Issues for the board, I should ensure that the sound recording device is set to Realtek HD Audio. Except that the board comes with no Realtek devices, but has the SigmaTel STAC9227, that’s great.

I have the Intel audio studio installed, along with the latest drivers, but no joy. The board has the audio headers plugged into the standard audio block that comes from the case, though I’ve tried the alternate setup with the slightly re-arranged pins (using the individual pins instead of the preformed block).

I have 5.1 surround headphones, so what I’d like to do is have them plugged into the back three connectors and just plug the microphone into the front audio plugin on the case. I’ve tried this setup as well as the plain old “1 connector for audio, 1 connector for microphone” setup as well.

Anyone seen this? Heck, anyone have the microphone going with this motherboard period?
