I have a dell inspiron 1300 laptop with windows xp. For the last 3 years since I got it I have problems with the sound when I make a video call. After about 3 minutes the person I'm talking to loses my sound. I find that when I use audio alone, I have no problem, but when trying to make a video call the problem arises. I have checked the audio settings and they are ok. Can anyone come up with an answer for me? I am using a Logitech communicate xps webcam with built in speaker.
