Yes, testing the latest code with real machines is highly
appreciated.  Try sound-unstable git tree, either master or
test/hda-migrate branch.
  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable.git

Alternatively you can build the external alsa-driver modules from
alsa-driver-unstable snapshot tarball, too
  ftp://ftp.suse.com/pub/people/tiwai/snapshot/alsa-driver-unstable-snapshot.tar.gz

Note that only the behavior of model=auto has been changed in the tree
above.  The other model behaviors of AD codecs are unchanged at all.
