Sound Problems I was at target and I bought the Logitech Quickcam Chat Webcam. I've noticed that compulsively in my videos there is a crackling sound that drowns out every other noise, for at least half or a majority of the video. I'm wondering how I can fix that?

That is a very good awnser go with him

RightSound™ Technology:
RightSound™ technology is a feature of Logitech’s new premium webcams that provides acoustic echo cancellation (AEC). This eliminates echo and feedback often created by a microphone and speakers that are in close proximity. Logitech includes this technology so you have clear, echo free audio while remaining completely headset free for an excellent audio experience.
What is AEC:
Acoustic Echo Cancellation, or AEC, is an advanced audio enhancing technology that improves your overall sound experience when talking to others via your computer. With today's audio and video Internet communication applications, you and the person you're talking to can both speak at the same time. It is possible that sounds from the remote party, when played over your computer's speakers, would be picked up by your microphone and sent back to the remote party. This problem is known as echo, and AEC is the technology needed to prevent it from interfering with the quality of your conversations.
AEC functionality:
AEC's purpose is to prevent sounds coming from your computer's speakers from being picked up by your microphone. This can be a significant problem with audio or video calling applications where the sound being inadvertently picked up by the microphone is the voice of the remote party who made them. Without AEC, this echo can detract from the quality of a call; in extreme situations, the echo can degrade the audio experience to the point where the audio is useless.
