           Summary: Logitech Fusion Webcam Mic regular sound distortion
    Kernel Version:  2.6.16.20
            Status: NEW
          Severity: normal
             Owner: perex at perex.cz
         Submitter: matt at dancingfrog.co.uk


Distribution: Ubuntu Dapper Drake, Redhat 3
Hardware Environment: Logitech Fusion USB Mic
Software Environment: Vanilla 2.6.16.20, Vanilla 2.6.11
Problem Description:

The USB mic for the Logitech Fusion webcam is detected and works using
snd_usb_audio.  There is however a annoying "loud click" for want of a better
description approximately every 5 seconds or so.  This happens on all
machines/distros (Ubuntu/RedHat 4 and Ubuntu with vanilla source kernel) I've
tested with the webcam.  

The issue must be with the usb_driver; reconfiguring ALSA to resample the USB
input has no effect.

Having looked around the web I see no other people reporting the issue; I have
no errors or interesting debug information.  Everything is great bar the regular
interrupt.  This is possible one of the poorest bug reports ever :-(

Steps to reproduce: plug in webcam and record sound.
