My internal microphone stopped working. I have done trouble shooting with Microsoft and Acer and gone through all steps of deleting and reinstalling drivers for going on 2 hours and it never works. Even if I connect with my wireless headphones there is no input sound recognition. I suggested to the support team that it could be hardware but they want me to send in the device for repair (device is only 6 months old) and I cannot afford to be without it for weeks. Has anyone experienced an input microphone failure. I am hoping there is something minor that I am overlooking.
