I plan on making some announcements during an event we are holding and have a microphone with a USB connecter so it can connect into the USB port of my laptop. However i cannot figure out a way to output whatever is being spoken into the microphone simultaneously through the speakers we have connected in the audio output jack of the laptop so that everyone can hear. Any software or settings that would allow me to do this? Urgent help is required the event is tomorrow. Thanks, Details: Operating System: Windows Vista
