[pulseaudio-discuss] Front mic not working properly

I'm totally stuck with a sound problem I fail to debug on my own.
Please tell me if my question should be directed to ubuntu or to this list.
Asus P5Q Motherboard with Realtec ALC1200 soundchip. Stereo speakers
plugged in to the rear output and headphone speaker/mic combo plugged in
to the front jacks. System: Ubuntu 12.10
Desired behaviour: Sound is played back on headphones AND rear speaker.
Front mic should "just-work"
As soon as I change the Microphone volume the Mic Boost jumps up,
leading to completely distorted sound. I think this is due to the setting
[Element Front Mic Boost]
in /usr/share/anaolog-input-front-mic.conf. If I change that to
volume=ignore, the volume problem goes away. Is this the right way to
solve the problem? - Why is the mic boost volume setting set to "merge"?
In my understanding only the Mic Volume should change when modifying
master microphone volume.
This is the biggest problem.
As soon as I plug in the front mic, Inside gnome-alsamixer the volume
for master, surround,center,lfe start to jump between on and off. Why is
the Front mic jack controlling these values? How can I debug this
behaviour? I just want them to stay the same, if the mic is plugged in
Inside the gnome volume settings, the output port starts to jump between
"Analog Output" and "Analog Headphones"
Any hints are greatly appreciated.
