[alsa-devel] snd-hda-intel AD1981 - the microphone doesn't work

[Robert Gonciarz]

Hi,

I've solved that problem. Feel free to publish it. The problem is that 
alsamixer doesn't show all the necessary options to turn mic on.

Thus I've installed the gnome alsa mixer and change the settings in the 
following way:

The microphone works but it creacks a little bit. It doesn't on Windows XP.
