After upgrade my webcam mic records fast, high pitched, and squeaky only in Skype (maybe Sound Recorder problem too)

  • 772

After an upgrade to 11.10 (kernel: Linux lucid 3.0.0-13-generic #22-Ubuntu) which probably also updated Skype to 2.2.35 (not sure because I never checked the version before) the sound that comes back from an echo test is very high pitched and squeaky. I'm not sure if when in a call if the other person can't hear or just doesn't know what they are hearing. I am using a USB Logitech C250

Audacity records fine, gmail video chat works fine, but if I start sound recorder I get a "Could not negotiate format", followed by "Could not get/set settings from/on resource". I don't know if this is a Skype problem or a wider Pulse problem.

My only real needs are the gmail and Audacity, though I have a couple of contacts that I can only Skype with.

11.10

    There is a bug open in Launchpad (have a look here)

    Comment #80 helped me:

    The problem is that the microphone is in the wrong sound rate by the pulse audio. As a user do the following:

    gedit $HOME/.pulse/daemon.conf

    and put the following line on the file:

     default-sample-rate = 16000

    save it, and then restart pulseaudio as a user with the following command

    pulseaudio --kill && pulseaudio --start

    This should solve the problem.

  2. I had slightly different problem with Skype, but the solution might be the same.

    Why can't Skype hear me?
