An Arch user seems to have had this problem as well, and there's a patch in this forum post:

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help, we really do appreciate it.

I found that the problem created when run skype fisrt, and even after you quit it the sound recorder have the same problem.
If i start sound recorder before run skype (after restart) mic works fine.

The following "procedure" fix the problem for skype (i don't know why this "magic" happens but works every time i tested!)

run and login to skype
open terminal
pulseaudio -k //to kill pulse audio
ps _A | grep skype //to finde skype pid
kill -9 *skypepid* //kill the pid i found
pulseaudio --start //start the daemon again
run skype and login, the mic sould work.

latest kernel update does not fix the issue. Maybe it's a pulseaudio bug?

It's a kernel bug.

I have the same problem with a logitech C310 with all distros using the kernel 3.0.

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Sorry, I'm not a developer so I don't know, how to test an upstream kernel on my (private but productive) machine.

Can I help with other things?

@Christian,

Thanks for the feedback.

Would it be possible for others affected by this bug to test the mainline kernel:

I am using oneiric, linux-image-3.0.0-12-generic 3.0.0-12.20 (latest) and have this same problem with a Logitech C310 webcam.
Apart from archlinux already mentioned, even redhat has this bug fixed!!! Here is the diff:
https://bugzilla.redhat.com/attachment.cgi?id=517377&action=diff

Please fix this in Ubuntu as well, just copy the patch from arch or redhat.

Yes, it's a kernel bug but who knows when it will be fixed, even the latest 3.1-rc4 kernel doesn't have the fix.
Please apply the patch to the oneiric ubuntu kernels, like redhat and archlinux are doing for some time now.
These are extremely popular cameras, and it's very embarassing to sound like mickey mouse with skype on oneiric installations.
How soon can you apply the patch?

heitjan, sl45sms, anyone else, what's your webcam's usb id? I just realized that the bug originator's camera was not included in the patch, so I'm adding it, please do lsusb and supply your webcam id if it's not found in the following patch.
For example, Webcam Pro 9000 is in the below patch, but the Quickcam Pro 9000 is not (usb id 046d:0990) but we can't be sure it's affected by the bug unless we hear about it. For now I added the Webcam C600 (046d:0808).

Found duplicates of this bug about other webcams and added a few more (including the C260) to the patch. So this will be a more complete fix than arch/redhat have, but they were faster to actually release the fix, hopefully Ubuntu will pick this up soon and relieve us from this serious webcam issue.

The C160 is not in the usb id repository http://www.linux-usb.org/usb.ids
what's the output of your "lsusb" command?

The output is "Bus 001 Device 003: ID 046d:0824 Logitech, Inc."

Does it help?

Yup, I'll add it to the patch later today.
Make sure to subscribe to bug #843431 and say you're affected (if you haven't already)

FYI: I added the 3.1.0-999-generic kernel and that took care of the Skype chipmunk problem. However, the chipmunk persists in Sound Recorder.

Where can someone download the 3.1.0-999-generic kernel ?
Also, is there a source package for it to try the patch on?

Sordna,

The latest release candidate is the best kernel to test. It can be found at:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-rc10-oneiric/

The following page has details on the mainline kernel:

@Sordna,

It would be great if you can update bug 843431 if you are able to test the mainline kernel.

I tested the mainline yesterday (uname gave me: 3.1.0-0301rc10-generic #201110190851) and still got the problem.

I wish Kurt provides more info about the mysterious 3.1.0-999-generic kernel and where to get it from, but I doubt it solves the issue since Kurt says sound recorder was still affected.

I see others have steered you toward http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/ as the source for the 3.1.0-999-generic kernel.

Anyway, that solved the problem only momentarily.

Basically everything having to do with the mic on the webcam is unstable. At one point, Sound Recorder was working normally while Skype was not - a complete reverse of the situation I had before. Now Sound Recorder is back to "chipmunk" mode and Skype won't play back anything on a test call even though the input meter shows good sound levels coming in from the mic.
