Public bug reported:
On the latest version of Ubuntu or Kubuntu microphone that connected to my
internal sound card is not working. I tried to set various parameters in
pulseaudio gui and played with alsamixer, trying to set the capture from the
microphone, but it did not help. Pulseaudio set a capture channel line-in, even
if I put up a mic pulseaudio gui. This leads to the fact that applications such
as skype do not get sound from the microphone.
In this Natty worked great, removing pulseaudio helps as well.
