The following packages should be deleted:
* alsa-driver.hda-intel.hda-codec-realtek * alsa-driver.hda-intel.hda-codec-realtek-git
The packages are broken (I tried updating the PKGBUILDs, unsucessfully), obsolete (as per http://www.alsa-project.org/main/index.php/Download#alsa-driver) and orphaned.
The matching wiki page should also be deleted: https://wiki.archlinux.org/index.php/Realtek_ALC892
