I have now made a small dkms package to help you verify if my theory is correct. The dkms version disables via_dmapos_patch in all cases. Please try the following:
* Make sure position_fix=1 is NOT present in /etc/modprobe.d/alsa-base.conf * Make sure you don't have any alsa driver overrides installed (e g linux-backports-modules, or the daily snapshot from ubuntu-audio-dev ppa) * Download and install http://people.canonical.com/~diwic/temp/alsa-intel-hda-diwic-via-dmapos-dkms_1.0.23.diwic_all.deb * Reboot * Test whether the error is gone or not, and report back here.
