Thanks --- this is a little better.

One more nit: it looks like this was reported, tested, and based on a
patch by Stefan Freyr.  Takashi, could you amend the message to
reflect that, or should the patch be resent?

Subject: ALSA: hda - add dock support for Thinkpad T430

I have a Lenovo ThinkPad T430 and an UltraBase Series 3 docking

Without this patch, if I plug my headphones into the jack on the
computer, everything works fine. The computer speakers mute and the
audio is played in the headphones. However, if I plug into the docking
station headphone jack the computer speakers are muted but there is no
audio in the headphones.
