I've developed a patch against alsa-driver-1.0.22.1 which should fix
this (which I've attached to this bug), which you can test as follows:

First make sure you don't have any versions of linux-backports-modules-
alsa installed:

apt-cache --names-only search linux-backports-modules-alsa | cut -f 1 -d
' ' | xargs sudo apt-get remove --purge

Now download alsa driver source and the patch, and compile and install a
patched version of the driver:

cd ~
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.22.1.tar.bz2
wget http://dl.dropbox.com/u/174251/alsa-driver-1.0.22.1-mb5.patch
tar xjf alsa-driver-1.0.22.1.tar.bz2
patch -p0 < alsa-driver-1.0.22.1-mb5.patch
cd alsa-driver-1.0.22.1
./configure
make
sudo make install

Now you need to reboot your machine. If this works I'll push the patch
upstream and hopefully we can get it applied to linux-backports-modules-
alsa as well.

Bug description:
I have managed how to manually mute internal speaker without muting headphones:
I dropped down to 0 the volume of Front/Surround/LFE (not muted them, otherwise also headphones will mute) and after un-mute the HP channel and rise volume.
