What should I do if my microphone does not work?

• Check if your microphone is selected as a recording device.
  Click Hardware and Sound in the Control Panel window, select the Recording tab in the Sound window, and check if there is a check mark on your desired microphone icon. If not, select the icon and click Set Default. If the icon is not displayed, make sure the microphone is properly connected to your VAIO computer.

• An external microphone with a 3-pole mini plug does not work with the headset compatible headphone jack .

• The microphone of your headset may not work with your VAIO computer. Use a Sony smartphone compatible headset.
