I've made a debian package for easy testing of the above patch. Could you please 1) uninstall the latest alsa driver. Confirm by checking "modinfo snd-hda-codec | grep ilename" which should not say anything with "updates" in it. 2) download and install http://people.canonical.com/~diwic/temp/alsa-hda-dkms-hpz200_0.1_all.deb 3) reboot and test. If successful, alsamixer should now have a switch "Auto-mute mode" which should be set to "Line Out+Speaker" and that should enable all automuting: HP -> Speaker, HP -> Line out and Line out -> Speaker.
