I recently upgraded to windows 7 from XP and the mic on my jack headset isn't being picked up. The headset speakers are found and they work fine. The "recording" tab of the Sound options says that there are "no audio devices are installed" even when show disabled/disconnected devices are checked. I tried updating my driver (already updated) and then reinstalling it. I have tried plugging the mic and headset into both the front panel and back panel. I have also tried a microsoft fix it service as well as the built-in troubleshooter. I have even plugged it in to another computer and it works fine.
I am using a logitech ClearChat Stereo headset (with jacks) and my video card is labeled as a High Definition Audio Device. My headset is recognized as speakers if that matters.
I've also posted on an official microsoft answers forum thing, I just wanted to see if you guys could help at all.
