PROBLEM: Microphone on Logitech QuickCam Ultra Vision outputs clicks

Hi,
I am very pleased with the progress of the Linux Kernel.  However for 
some time now I have been having trouble with the sound from my Web Cam 
microphone when using Skype. This problem also exists with Audacity and 
therefore seems to be a kernel related problem.  I have attached a 
document that details all the information that I think you will need.  I 
have also attached a sound file from Audacity that illustrates the problem.

I hope that what I have supplied helps clarify my problem and show where 
the problem could be.

All the Best

Sam Colegrove

This is a known hardware problem with certain Logitech webcams.
Logitech's Windows driver works around this by filtering out the clicks;
they have not written a Linux driver that would do the same.
