I installed Skype 18.104.22.168 in my Lubuntu 12.04. The internal mic is not working, while the external mic is. At the same time, other recording software (like gnome sound recorder, audacity or guvcview) are working ok with both inputs (internal and external).
Do you have any idea why this can be?
In the Skype configuration, 'allowing Skype to manage my volume control' is unchecked. If I check it, Skype turns mic and boost volume to the maximum, but it's not good (a lot of cracks and my voice on the background almost inaudible).
