Jerone, I don't think this is a generic bug. PulseAudio is trying to do the right thing, but as I mentioned in a previous bug, the auto-generated HW profiles only work as well as the information Pulse is fed.

On my 13" Macbook running Karmic Beta, my default Hardware Profile as displayed by gnome-volume-control preferences, is "Analog Stereo Duplux". The displayed soundcard icon includes the following text:

Internal Audio
1 Output / 1 Input
Analog Stereo Duplex

If I click the "Input" tab, I see single device listed "Internal Audio Analog Stereo". I also see a combo box for "Connector" which allows me to switch between "Line-In" ( the usual external mic connector ) and "Microphone".

So, in theory, if ALSA reports things correctly *and* your kernel version of your ALSA codec fully supports your system, it should be possible to switch inputs via the gnome-volume-control preferences.

That said, this *almost* works on my machine. I'm able to capture sound via the microphone, but when I re-configure to capture from the Line-In, I had problems.
