Never mind about "Function ID" entry.  It's just a new line that was
added recently.  function_id=1 means it's an audio codec.

The way HDMI is supported are mainly either through the same audio
codec (ALC889A) or through a dedicated HDMI codec.  In the former
case, you'll likely see a word "HDMI" in the digital output pin of the
codec proc file.  In the latter case, you must have a different codec
chip connected to the HD-audio bus with a different codec address
number.
