Summary:                    model is not autodetected correctly
Description: 
I am using a Fujitsu-Siemens Amilo M3438G (Datasheet here:
http://www.fujitsu-siemens.com/Resources/59/562938810.pdf )

When I load the module via modprobe snd-hda-intel I get the following
controls in alsamixer: 
playback: PCM, Headphones, Internal Speaker, CD, Mic
capture: 3x Capture
I can not get the Microphone to work, no matter what I select as Input
Source for the Capture channels.

When I use modprobe snd-hda-intel model=auto I get
playback: PCM, front(controls headphones), side(controls internal
speaker), center, lfe, internal mic, mic, ...
capture: 3x Capture
The Microphone (Internal, or external if connected) works when I unmute
the first capture channel and set its input source to Front Mic.
Sometimes the center channel controls the speaker at the bottom of the
laptop, sometimes it doesnt, seems kind of random.

Documentation states, that model=auto is the default, but as you can see
it is not

OK, then let's get back to the beginning.

Without any model option, the recording from mic works when you raise
"Capture Volume" and choose "Front Mic" as the capture source?

No, it doesn't. When I do not pass any model option I cannot record any
sound from the microphone. I tried all three capture channels and all
input sources. The first capture channel has static noise on it, the other
two are just silent.

With models auto, 6stack and lg I can record sound by raising the first
capture volume and selecting front mic.
