I have Ubuntu 11.10 + Logitech Webcam Pro 9000 + Skype and I'm experiencing the "chipmunk" sound during test call.
My workaround is to go to the Skype options "Video Devices" tab and click "Test" to enable webcam (this turns on the red light in the webcam). Now, if I make a test call, the sound is recorded normally. I have not investigated this any more, but for now it works for me.
