I have similar issue with microphone too. But in my case I can record from camera's microphone with 'sound recorder', but resulting recording seems like the recording source was playing very fast.
My camera is Logitech C210 (ID 046d:0819) and it worked ok on Natty

I can also confirm the same behavior as Alex Popovskiy. It either works but plays to fast (high pitch) or it doesn't work at all.

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

Latest kernel update didn't solve the problem for me

Latest 3.0.0-11.18 kernel didn't help for me either. I am using a Logitech C910. Camera works but not the microphone.

I ran some tests and here is what I found: I can record normal sound from webcam's microphone, but only once after reboot. Any subsequent attempts will record high pitch garbage. I've also noticed that track duration counter in gnome-sound-recorder lags (one second in counter is like 2-3 normal seconds) as well as input level indicator. There is also noticeable sound glitch when starting first (normal) record, so maybe this bug is not about the kernel but pulseaudio's fault.

I was wrong about pulseaudio. Now I'm sure its 3.x kernel bug/regression. I've just tested 3 different kernels: 3.0.0 (current oneiric) - no mic input/glitches, 3.1-rc4 (from mainline ppa) - same as above, 2.6.38 (from natty) - mic works flawlessly.

I did a fresh install of Ubuntu Beta 2 and the microphone now works for me. I'll let the original reporter status this
and close it if he no longer has the issue.

Microphone still doesn't work after cold boot or reboot from windows, but I can get it working by reconnecting the webcam now. It is a workaround, but not really comfortable :(

I confirm the same problem with a Logitech C310.

No change for me with new kernel

Adding patch that fixes the issue. Patch taken from kernel bug #35922 as well as archlinux and redhat who already fixed the issue in their kernels. I added many more affected cameras in the present patch. I hope we see it applied to oneiric kernels soon, otherwise the wikis that report how nicely all these Logitech cameras play with linux should be rewritten because the audio has been terribly broken, while it worked fine with natty.

same problem with a Logitech C310

I can verify that the patch works, with a Logitech C310.

how can I apply the patch?

@sordna,

It has passed testing and is currently waiting to be copied from -proposed to -updates.

Great, I got the update and can confirm linux-image-3.0.0-14-generic fixes the problem on my C310, and should do the same for the all webcams in the earlier patch: (C200, C250, C270, C300, C310, B/C500, Pro 9000)

For other webcams like the C600, C905, the E3500 and others, people will have to wait for ubuntu kernel 3.0.0-15 (assuming will be based on official linux kernel 3.0.11 or later, which has the latest, more complete patch)

A newly released kernel fixes the problem for the original submitter (and others).

Same problem for me, mic doesnt work in sound settings or skype. Kernel linux-image-3.0.0-14-generic didn't fix the problem.

I've got Hercules Duplex Exchange Usb camera with built in MIC, not sure how to get the ID.

I can confirm that 3.0.0-14-server fixes the chipmunk sound in my case, my usb webcam is the following (using lsusb):

046d:0809 Logitech, Inc. Webcam Pro 9000

I reversed the 2 workarounds that were posted earlier, Installed 3.0.0-14-generic and can confirm that it appears to be fixed so far.
Webcam Pro 9000

I have tested 3.014 kernel and i think it sill doesnt fix the bug for Logitech Webcam B500.

Bus 001 Device 006: ID 046d:0807 Logitech, Inc. Webcam B500

as Sergey wrote on 2011-12-13:, mic doesnt work in sound settings or skype.

The kernel 3.0.0-14-generic works for me :)
Webcam Pro 9000

Sergey, the Hercules Dualpix webcap fix is in the 3.0.0-14 kernel, to get the ID do: lsusb on a terminal and you should see a device with ID 06f8:0804

Carlos, the B500 fix is in this kernel as well. I suspect you are having some other issue or haven't configured the applications correctly. Maybe you need to use pavucontrol and asociatiate your webcam to your applications.

Same problem as Sergey: 3.0.0-14 kernel from updates and 3.0.0-15 kernel from proposed do not fix the microphone problem for Hercules Dualpix Exchange webcam.

@sordna : Indeed, the ID associated to the webcam in the patch from comment #74 is not correct:
lsusb says
ID 06f8:3005 Guillemot Corp. Hercules Dualpix Exchange

@Brad Figg : is it possible to included to fix this in kernel 3.0.0-15 before it goes to ubuntu-updates repository.

Thanks a lot

Serge, you are right, looks like the patch had the ID of the Hercules Dualpix Exchange wrong as you can see here:
http://kernel.opensuse.org/cgit/kernel/commit/?id=2394d67e446bf616a0885167d5f0d397bdacfdfc

The patch says USB_DEVICE(0x06f8, 0x0804) but it should instead say USB_DEVICE(0x06f8, 0x3005)
I suggest you email the 2 people you see in the Sign-Off line of the above patch, and ask them to fix it. This should be fixed in the official Linux Kernel rather Ubuntu.

Thanks sordna, after trying some changes in the Skype settings, now it works with the Ubuntu kernel 3.0.0-14

Follows comments 110, 115 and 116.
Fix for Hercules Dualpix webcams sold after 2009 has been included in kernel 3.2.1.
The new version of quirks.c includes many fixes for new devices.

See http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=blob;f=drivers/usb/core/quirks.c;h=4c65eb6a867a1974d8596caaccc9d3d3f15152ef;hb=b8ed9e5b8c34dc9fb1882669e45b21e3d0194881

Could this new version of quiks.c file be included in next kernel update for oneiric ?
Must I open a new bug for this ?

I've just found an excellent little web cam that works out of the box in Oneiric. 1.3Mpixel native resolution, cost £6 delivered UK.
http://www.ebay.co.uk/itm/260830581589?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

You'll need to select the web cam as microphone input in System Settings>Sound then Input tab. Works with just a USB plug, no separate microphone plug required.

"There are test kernels at: http://people.canonical.com/~bradf/lp843431"

Brad, I'd like to try but you do not include the non-arch specific headers. Without a full set of headers, I cannot compile my nvidia driver and I lose my audio output device.

For your information, I had the same sound problem with
kernel 3.0.0.16-generic-pae
Bus 001 Device 003: ID 06f8:300c Guillemot Corp. (Hercules "Classic Silver" according to sound settings)

I tried both solutions (add a daemon.conf file and usbcore.autosuspend=-1), then update grub and restart skype and now it's fixed. Thank you.

The only solution to make microphone work is to install linux-backports-modules-alsa-generic...

Just go to:

Menu / System / Administration / Synaptic Package Manager

And search and mark for installation:

linux-backports-modules-alsa-generic

tip: if you have multiple versions click on the first and read the description which should inform what name to install...

If after the reboot and mic mute is off, still does not work, just go to terminal and type:

sudo nano /etc/modprobe.d/alsa-base.conf

and add or change the following:

options snd-hda-intel model=auto enable=yes

Then Ctrl+X, type Y to write and exit, reboot and mic will work.

Bye and have lots of fun with Ubuntu (the best).

thanks jmim. this last one was what worked for me (editing alsa-base.conf). microphone now works properly.

I had the same issue with C910 camera + mic.

I make it work using comment #123 solution, just the alsa-base.conf modification, did not install any backported module.
on 3.2.0-23-generic #36-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 12.04

I might add that in Ubuntu Sound preferences I've two input device, referring to that only device. If I keep the first selected, as in attached screenshot, it works. If I switch to the second one, it got back to the usual issue.

Logitech c270 don't work in Linux 3.5 RC again. Same problem?

@GreatKir

bug 1018020 has been opened for the issue in 3.5

Hi!

My USB mic was working fine. It is a Zoom H2.

Then last week it went chipmonk. I tried comment 80:

gedit $HOME/.pulse/daemon.conf
and put the following line on the file:
Code:
default-sample-rate = 16000
save it, and then restart pulseaudio as a user with the following command

But got:
Could not find the file “/home/ME/.pulse/daemon.conf”

I then tried comment 93
"usbcore.autosuspend=-1"

And it made me less chipmonk, but still a bit chipmonk.

Any ideas? Why has this suddenly happened?!

Aha! So I don't know what went wrong. But here is a solution:

http://blog.anidear.com/2011/10/fixing-chipmunk-sound-on-skype.html

Depending on what mic you are using you might have to change the settings through the menu.

Scratch that, it works for a couple of minutes and then screws up.

A hint: I switched from a USB 3.0 to one of the few USB 2.0 ports I still have... and magically the issue disappears. Can this really be related to the use of a USB 3.0 port?

I all, i just run a fresh install of xubuntu 18 and the issue is still there
$ lsusb
Bus 003 Device 002: ID 046d:0809 Logitech, Inc. Webcam Pro 9000
$ uname -a
Linux MS-7756 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I'm affraid it's not fixed...because i still got chipmunks on xubuntu 18 fresh install

I take a look at kernel source code ad see that the patch #37 is not applied on kernel 4.15.0-20-generic

Emmanuel,

This quirk should apply to your webcam:
static const struct usb_device_id usb_interface_quirk_list[] = {
        /* Logitech UVC Cameras */
        { USB_VENDOR_AND_INTERFACE_INFO(0x046d, USB_CLASS_VIDEO, 1, 0),
          .driver_info = USB_QUIRK_RESET_RESUME },

        { } /* terminating entry must be last */
};

Hi Kai-Heng,
Yes, you are right, but the real question is why does this disappear from the latest kernel ?
It was in the previous. So i suggest to that the bug need to be reopened in order for dev to merge from previous branch and have all "non stereo" webcam working again.
I unfortunatly can't reopen it myself (or i don't know how to do it).
Regards,

The quirk I pointed in #135 is in latest kernel.

May be a good idea to try older kernels in [0] to make sure it's a regression.

[0] http://kernel.ubuntu.com/~kernel-ppa/mainline/

I'll check that but if you look at
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/drivers/usb/core/quirks.c?h=v4.15.18
you can see that devices listed in #37 are not there and for me :
/* Logitech Quickcam Pro 9000 */
{ USB_DEVICE(0x046d, 0x0990), .driver_info = USB_QUIRK_RESET_RESUME },
is not there !!!
but
{ USB_VENDOR_AND_INTERFACE_INFO(0x046d, USB_CLASS_VIDEO, 1, 0), .driver_info = USB_QUIRK_RESET_RESUME },

is!!
as additional information :
- Skype is working well but arecord no, audacity neither.
- It was working fine under ubuntu 16.04 but not 18.04
I'll will go into further investigation next weekend...

Sounds like a regression introduced between Linux v4.4 and v4.15.
Please find the first first non-working -rc* kernel between 4.4 and 4.15 in [1].

Hi, due to a computer failure, i'm not able to test this right now... and i don't known when it could be possible.
I apologize for that.

Well... Same bug here - B500 cam on Mint 18.3 with 4.15 or 4.8 kernels.
But works perfectly with 4.4

Can I help somehow (as an not really "technological" person)?

i'm having this issue on 18.10 as well, 4.18.0-13-generic with a Logitech C310 (046d:081b). it's been an issue since 18.04 and older for me; i can't remember when it worked without issue, but it did at some point.

it appears this commit [0] is the cause as after restoring the specific USB_QUIRK_RESET_RESUME line for my model and recompiling the kernel i cannot reproduce the squeaky-voice issue. with the standard kernel i can reliably reproduce it with Audacity by recording, stopping the recording, then starting another recording - after ~3 "correct" recordings the pitch changes.

with the recompiled kernel it appears the device is being "reset" for each recording:

usb 2-1.6: reset high-speed USB device number 4 using ehci-pci

i do not see this when using the standard 4.18.0-13-generic kernel, so i'm guessing this is what the quirk does and usb_interface_quirk_list in quirks.c isn't catching my webcam. i believe there should be a match based on the code; lsusb output includes the following Interface which looks like it matches the call (USB_VENDOR_AND_INTERFACE_INFO(0x046d, USB_CLASS_VIDEO, 1, 0)) since USB_CLASS_VIDEO is 0x0e which matches the bInterfaceClass, and subclass/protocol also match. note that this is not the first interface in the lsusb output, not sure if that matters.

[0] https://github.com/torvalds/linux/commit/e387ef5c47ddeaeaa3cbdc54424cdb7a28dae2c0

perhaps i spoke to soon - even with the kernel changes i'm able to reproduce the squeaky-voice issue.

i've also tried creating ~/.pulse/daemon.conf with default-sample-rate = 16000 which does not fix the issue.

I have had this issue with my C270 on Windows and now on Ubuntu 20.04. So it's mainly a Logitech issue, but on Windows I fixed it by fixing the mic on 16000 hz. On Ubuntu I tried chaging etc/pulse/daemon.conf to ; default-sample-rate = 16000
; alternate-sample-rate = 16000
and it did not work. Only for a little while.

Looks like there's a way to set the sample rate for a particular device explicitly, and that's what is called for in this case:
