Question about Logitech Quickcam Chat Webcam
When I answer a video call the other person can see and hear me no problem, I can see them but I can't hear them, all I get is a load of noisy squealing and when I turn down the sound at my end, they can still hear me fine but without the noise, and when I speak I hear an echo back, any ideas?
Durring video conferencing with MSN
Messenger, I can't hear my friend and he can't hear me. Or I can hear
them but they can't hear me. What's wrong?

Test the Microphone in Sound Recorder
While using MSN Messenger it is the messenger program, not the camera software, that negotiates the audio streams between two MSN Messenger Clients. Although we cannot directly support audio issues in MSN Messenger, the following steps have been known to resolve and improve audio issues in MSN Messenger. For further information, please consult the help documents associated with MSN Messenger.
Test Your Networking Router
You can also test to see if your router is causing audio issues by either physically bypassing your router and connecting directly to your cable/DSL modem or by setting up your computer as the DMZ (de-militarized zone). If you are a novice networking user, it is not recommended that you leave your computer in the DMZ state for extended period as that may leave your computer vulnerable to attack. However, you may briefly configure your computer as the DMZ to determine if your network settings are causing the audio issues. For DMZ setup instructions, please consult your router's documentation.
Enable Universal Plug and Play (UPnP) on both Windows XP and Your Router.
If either of the above steps resolves the no audio problem, try the following steps.
If your router does not support UPnP or you still get no audio after enabling UPnP on both Windows XP and your router, you must manually open all UDP ports between 5004 and 65535. This is because the audio streams are sent dynamically using that range of ports. Without a dynamic way to open those ports like UPnP, there is no way for MSN Messenger to successfully negotiate the audio stream. Consult your router's documentation for instructions to manually open these required ports.
If you are still experiencing audio issues within MSN Messenger, and you have verified that the microphone is working in Sound Recorder, contact MSN Messenger Support.
This article covers Accoustic Echo Canncellation (AEC) and how it works.

This article applies to the following platforms:

Windows® Media Center Home
Accoustic EchoCancellation (AEC)'s purpose is to prevent sounds from your computer's speakers to be picked up by your microphone. This can be a significant problem with audio or video calling applications where the voices or sounds from other parties of the call is being inadvertently picked up by the microphone and fed back into the call, creating echo and other sound distortions. Without AEC, this echo can detract from the quality of a call and in extreme situations, the echo can degrade the audio experience to the point where the audio is useless.
To prevent this from happening, the AEC component monitors sounds being played by your computer's speakers while monitoring the incoming sound picked up by your computer's microphone. The AEC module takes the outgoing and incoming sound signals and compares them to determine if echo is present. If echo is found, it is subtracted before the audio from the microphone is sent to the requesting application. This will result in the remote party only hearing you speak, without being distracted by hearing their own voice echo back to them.
When enabled, echo is eliminated for the recipient of the audio/video message. For echo free chatting, both parties need to have a RightSound technology enabled web camera that supports the AEC feature.
