I have a logitech messenger web cam with built in microphone. On no. 2 pc everything works as it should. On new pc [No. 1] when I try for a video call I can be seen [not a pretty sight] and heard. The person at the other end can be seen but not heard. This pc can stream video and sound from the net ok. If I start a voice call the other person can be heard ok and if I now click on the webcam I can see and hear the other person. All settings seem to be ok but I would like to sort this out if anyone can suggest anything. Using Windows live messenger. XP Pro SP2.
