Bug#661830: [3.1 -> 3.2.7 regression] ALC269: plugging in headphones does not mute main speaker

Thanks for reporting it. Can you test with Takashi Iwai's for-next
branch? It works like this:
0. Prerequisites:
apt-get install git build-essential
1. Get the kernel source tree, if you don't already have a copy
with history.
git clone \
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
2. Retrieve the sound tree:
cd linux
git remote add -f sound \
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git
3. Check out the for-next branch and test.
git checkout sound/for-next
cp /boot/config-$(uname -r) .config; # current configuration
make localmodconfig; # optional: minimize configuration
make deb-pkg; # optionally with -j<num> for parallel build
dpkg -i ../<name of package>
reboot
Please also attach output from "alsa-info.sh --no-upload" on an
affected and an unaffected kernel, so we can get to know your
sound card better. The alsa-info.sh script can be found at [1].
Sincerely,
Jonathan
