Sorry Takashi, I did try both patches but neither seemed to work.  I 
didn't get any time since then to confirm it wasn't something dumb on my 
side.  After failing to see anything from the recompile / re-install and 
modprobing snd-hda-intel out and back in, running hda-verb as described 
did continue to bring the audio right up.

I should check that the mixer VID/PID actually is ...889 on this machine.
