While watching the input volume meter from my webcam in pavucontrol, it maxes out with a short (100ms or so) cracking sound every ~3 seconds, independently of the ambient sound. How can I get rid of it?

Looks like this has already been reported, but the project was abandoned. I don't suppose it would help to bribe with a bounty? :)

$ lsusb | grep -i cam
Bus 002 Device 004: ID 046d:08ce Logitech, Inc. QuickCam Pro 5000

From the Linux UVC driver footnotes:

1 First and second generation Logitech webcams suffer from firmware bug which make the camera somehow unstable. As the issue is timing-related, the exact impact of the bug on a particular user can't be predicted. If you plan to buy a Logitech webcam, consider getting one of the models not affected by the bug. More information about the issue, including possible workarounds, are available on the QuickCam Team website.

2 Starting at version 2.6.22, the Linux kernel includes a USB audio bug fix which triggers a (possibly identical to the above) bug in first and second generation Logitech webcams. See the Linux UVC wiki for a workaround.

Both references are down, so I guess that's it for this camera.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

Looking at the bug report, unless this is resolved with a newer kernel, looks like a dead end. Can you try a newer kernel and report back ? – bodhi.zazen Feb 28 '12 at 5:23

Apparently this is a firmware bug (see the bug report). Buying a new webcam seems the only solution.
