I have a compaq presario v3700 with windows xp.It has conexant high definition as audio. I plug in my headset. It works in terms of audio hearing on headset but u can also hear it on computer. Then my microphone doesnt work at all. I've checked through control panel sound devices to test hardware but it's not picking up voice or audio eventhough I've changed to stereo headphones in properties.? Is it the driver missing?

Hi,

Don't think its the drivers, because you can hear audio.

Do you have your mic with your headset or separatedly? If with headset, maybe your headset has a physical switch where you can enable/disable mic (seen this feature on some Locitech headsets).

You can also check whether you have Mic muted in your audio control panel. Go to Control Panel, open Sounds and Devices and File - Properties if I remember correctly (sorry, I have Vista now) and put a check before Mic property to bring out the Mic volume level bar to see whether it's muted or not.

Hope this helps,
Tom
