I'm actually unsure on upstream policy on this one. I think I've seen both variants.

Actually, the very latest alsa drivers might contain a setting for auto-mute. Would it be possible for you to follow these instructions:
https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules , reboot, start alsamixer and see if you have an "auto-mute" setting, and if so, make sure the setting is right, then test again?

David -- I don't see an an auto-mute setting when installing the latest drives. However, it is possible to mute the internal speaker by selecting "Analog Output" rather then the default "Analog Speaker" in Output settings

Hmm, I think this patch will help.

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.

David -- I have follow your instructions and found the patch is working correctly. The internal speaker is now muted when the front or rear audio ports are used.

This patch has been included upstream in kernel 3.0-rc5. A PPA of of this kernel is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/

As noted in comment #10, the patch to resolve this issue was included upstream as ov v3.0-rc5:

ubuntu-oneiric$ git describe --contains d2a19da79d3ea5b7859248b0f132c479ed4505e2

We've already rebased and uploaded the latest Oneiric 3.0.0-7.8 linux kernel which was rebased on the final v3.0 upstream kernel. As such this patch should already be included in the latest Oneiric kernel upload. Thus, I'm marking the actively developed linux task from Fix Committed to Fix Released. Thanks.
