Internal Microphone not working on Arch (Dell Studio 1558)

Question

Hello community,
I never managed to get the internal microphone of my Dell Studio 1558 to work with ArchLinux 64Bit. I know that the soundhip of Dell Notebooks is a bit tricky sometimes. I already tried several configurations in the alsamixer. Unfortunately there are not much possibilites. In this Screenshot you can see all mixers that are displayed in alsamixer. No matter what I do, the microphone will never work. Of course it would not work with pulseaudio, too.
I also tried several configurations in /etc/modprobe.d/modprobe.conf
options snd-hda-intel model=6stack-dell
options snd-hda-intel model=3stack-dell
options snd-hda-intel model=dell
To make sure the mic is not borken and works on Linux I booted a 32Bit Xubuntu 11.04 Live system. The Microphone worked there and Alsamixer gave me many more mixers there.
I don't know what info to provide... At least here is cat /proc/asound/cards. I doubt it's helpful though.
cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf0b00000 irq 43
Help is appreciated Thanks already.

A long time ago I had a problem with the microphone in my Dell Studio 1737. When I finally got it working, I wrote down how I did it. Now I wish I had been more of a chatterbox... Anyway, here's my note:
/etc/asound.state
control.11 {
value.0 true
value.1 true
Hope you can make heads or tails of it.
