Looking at your screenshot, I wonder why you have Microphone set as default recording device if you are trying to record sound from Speakers.
Obviously I don't know your setup, but I would right-click on a blank space in the Recording tab and tick Show Disabled and Disconnected Devices, then set either Speakers or StereoMix (as appropriate for your system), if they become available.
Sorry if I've got the wrong end of the stick!
