> My setup:
> 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"

> 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 or not.

"Analog Output" and "Analog Headphones"

This look like problem in Jack detection of the headphone and Mic Jack of
front audio panel

alsamixer -c0

Does the playback switch change rapidly on and off in alsamixer ?

Do your computer chassis have a hda front audio panel and you connect them
to the front audio connector of the motherboard according to the user
manual ?

Does it help if you disabled the automute switch ?
