Hello Gigi,
Thank you for your response.
I understand your frustration. However, I would suggest you to try configuring microphone levels and check if it helps. Please follow these steps to set the microphone levels:
a. From the Start screen, type sound to open the "Search" charm, and then select "Sound" from the search results. The "Sound" window opens.
b. Click the "Recording" tab.
c. Select the microphone, and then click "Properties".
d. Click the "Advanced" tab.
e. Remove the check from the box next to "Allow applications to take exclusive control of this device".
f. Click the "Levels" tab.
g. Change the microphone level to 100 and the "Microphone Boost" to +10.0dB. Click apply and ok.
h. Disconnect and reconnect the microphone. Then, check the microphone.
I hope this information helps.
Please do let us know if you need any further assistance.
Thank you
