I cannot get the microphone on my headset to work on my Motion Computing Tablet PC, Win XP. I know there is nothing wrong with the mic because it works on my other computer. Here is what happened. The microphone has a standard plug and it previously worked until I purchased a Logitech USB headset and used it on this computer. I subsequently returned the Logitech headset and now I cannot get the microphone on my original headset to work. The sound works, but the mic does not work. I also want to mention that I used the USB Logitech microphone on my OTHER computer, with Win 2000, and my old mic still works on it. I've checked the microphone settings and the microphone is NOT muted. Can anyone please tell me what the problem might be? Thank you!
