 I am using a Dell Latitude D810 laptop with a USB QuickCam Deluxe for
 Notebooks webcam & microphone.

 This problem appeared in Skype for Linux.  When I talked to other people
 they and I could hear clicking noise every 4-6 seconds.  There were other
 people on Skype forums who experienced similar problems.  Nothing helped
 me.

 While trying to resolve this issue, I ran PulseAudio Volume Control and
 opened the Input Devices tab.  There is microphone signal strength meter
 (a blue line that jumps back and forth).  Most of the time the blue line
 is at the left edge unless I speak loudly.  However, from time to time
 (within a few seconds) this line jumps to 100% even though I make no
 sounds.  Then the line gradually goes back to the left within less than a
 second.  This behaviour is independent from the sensitivity settings.  I
 attach a file with the sensitivity set to 10% but the signal level still
 jumps to 100%.

 Skype is not loaded, so it is not related to it.  There is nothing wrong
 with the hardware because the microphone works fine in Windows XP (using
 the native Windows driver).
