Speakers, on the other hand, are output devices, because a computer sends audio to the device, not the other way around.
If you have more than one audio input device on your computer, you need to select which one you'll be using at any given time, by using the Windows audio control device.
Instructions:1 Right-click one time on the "Speakers" icon in your system tray.
2 Click the "Recording Devices" link to open the Windows audio control device, which displays a list of all lines on your sound card. A "line" is another word for an input, and each input device you have connected to your sound card will appear in the window on screen.
3 Right-click and select "Show Disabled Devices" if it is not currently enabled.
4 Right-click on the listing for the audio input line on your sound card that is currently active. Click "Disable." This will disable that particular line.
5 Right-click on the listing for the audio input line on your sound card that you'd like to start using. Click "Enable." This will enable that particular line. Any recording program you use will then be able to use the device that is connected to that line. You can repeat Step 3 and Step 4 to continue to change audio input selection as needed on your computer.
