I'm a Mom with a lenovo 3000 N200 with integrated webcam so that I can see and hear my son in Australia when I use MSN Messenger video call. Problem is I can see him but can't hear him and he can't hear me. I can't work out what I'm doing wrong. Is there an inbuilt microphone on the lenovo or is it as simple as that I need to buy and connect a mic?
