Or, it might be some ALC889 COEF fixup.
In anyway, try sound git tree, too
    git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

Or you can build alsa-driver externally without upgrading the whole
kernel.  I don't know the status of Fedora, but SUSE or Ubuntu provide
the update kernel module from the latest alsa-driver snapshot.

The latest alsa-driver snapshot tarball is found at
    ftp://ftp.suse.com/pub/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
