Sound not working with ALC889 in FreeBSD 10

[Zenny]

Sound is not working in FreeBSD-10 with GENERIC kernel. I checked the
available online resources and handbook (
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/sound-setup.html).

I have appended snd_hda_enable="YES" in/boot/loader.conf

Also tried to append /boot/device.hints with line
<hint.hdac.0.cad0.nid20.config="as=3 seq=15">, but with no luck.

Any inputs appreciated! Thanks!
