The Configure option is not available because you don't have the speaker installed or enabled. In order to fix this, go to Start > Control Panel > Hardware and Sound > Sound > Recording, right-click on the window and check Show Disabled Devices. After that, right-click on the Stereo Mix device and select Enable. If you don't see the device, you will need to reinstall the audio driver. Go to Start, type dxdiag and open the utility. Click the Sound tab, check the information below Device and go to the developer website and download and install the latest drivers available.
