Use Skype With a Headset While Sending Music to Your Speakers

If you want to make calls on skype but don't want your conversation blasting out of your PC speakers, there is a simple way to set it up.

Steps

Purchase a USB headset and connect it to a USB port on your PC.
Connect your PC speakers to your sound card as you normally would.
Open the Skype application.
Go to the Tools menu, then choose Options
Select your USB headset as the device for audio in and out.
Close this menu.
Open your Windows Control Panel
Open the Sounds and Audio Devices option
Select your sound card (not the USB headset) as the sound playback default device.
