I recently upgraded to windows 10 TP and found it to be a little too buggy, so I downgraded back to 8.1. Upon going back to 8.1 my microphone no longer works for a regular phone call. It works on speaker phone, but when I turn speaker phone off the person I call cant hear anything I say or do. I have restored and factory reset multiple times to try to fix this and nothing seems to work. I thought it was maybe just a bad microphone but the mic works for everything else I do besides Cortana. I use the mic for google search via the google app and it works, I use it for voice recorder app and it works, I use it to record video and it works, etc. That leads me to believe its something software based because the mic seems to be working for everything else.
If anyone can help it would be GREATLY appreciated.
