Bug Description

I recently updated to Ubuntu 11.10 beta2 and noticed my microphone on my Logitech Webcam Pro 9000 was not working in skype. I looked farther and it doesn't work properly in sound recorder either. On a fresh boot all I get is static. If I plug in the webcam after the computer is on it will record what I am saying, but in a really fast chipmunk type sound.

Please run the following command in a terminal, with your webcam plugged in, so we can get some more information about your hardware: apport-collect 871543

Thanks.

I see the same problem.

To get the sampling right for pulseaudio, I had to modify the default-sampling-rate in daemon.conf in ~/.pulse and /etc/pulse to 96000. Restarting pulseaudio fixed the problem when using arecord and aplay. Skype seems to reset the sampling rate so that I still get the chipmunk sounding voice after skype starts.

In addition, I find my specification of the default-sampling-rate seems to be ignored on ubuntu startup because I have to kill pulseaudio and restart it so that arecord and aplay do not record the chipmunk sound.

My guess is that this will happen with any USB microphone that does not conform to the default pulseaudio sampling rate.

Thanks!

I have the exact same issue, with the same Webcam, Logitech Webcam Pro 9000. Worked perfectly on 11.04, but now no audio or chipmunk audio. Am unable to use Skype ( which I use for business ) at the moment as a result.

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).
