Comment 34 for bug 433055

Thanks everyone for the solutions:

I upgraded my kubuntu from 9.04 to 9.10 and Skype 2.1 microphone stopped working. I did lots of research and found the solution here.

1) I just remove skype:
sudo apt-get purge skype-common
sudo apt-get purge skype-static
sudo apt-get purge skype

2) Installed padevchooser (it also installed pulseaudio)
sudo apt-get install padevchooser

3) Open Volume mixer window by right clicking master volume icon on taskbar
4) Configured mic volume
5) did a test call on Skype 2.1

BINGO!!! All worked well.

Cheers,
Ajay Lulia.
