In the system tray at the bottom right of the screen, right click on the volume icon and click on Recording Devices. Make sure that your microphone is set to the default device.

There is 3 things, Microphone (3-USB Audio Device), Microphone (Sound Blaster Recon3Di), and What U Hear (Sound Blaster Recon3Di). Which one ?
