[Bug 580006] Re: Headphone jack sense missing on Realtek ALC269

** Description changed:

  It seems as though the channel for enabling/disabling headphone jack
  sense is missing for this card (looked for it in alsamixer and kmix,
  found nothing). There are separate channels "Headphone" and "Speaker".
  Both work as intended, I can change the volume and mute both channels
  independently and get the expected results. I'm just missing the
  functionality that the internal speaker is automatically disabled when a
  headphone is plugged in (and re-enabled when it's NOT plugged in).

  There's a mute button on the chassis (produces no key events with xev)
  which mutes the internal speakers, but not the headphone channel. When
  using this button to mute, the mixer doesn't show that the speaker is
  muted, though.

  The machine is a Lenovo ThinkPad SL510 (with the latest BIOS installed,
  1.35-1.19). alsamixer reports the card as "HDA Intel", chip "Intel G45
  DEVCTG". /proc/asound/card0/codec#0 says "Codec: Realtek ALC269".

  lspci says:
  00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

  I compared the contents of /proc/asound/card*/codec#* with and without a headphone plugged in:

  jensi at tp:~$ cat /proc/asound/card*/codec#* > no-headphone
  jensi at tp:~$ cat /proc/asound/card*/codec#* > headphone
  jensi at tp:~$ diff -U 2 no-headphone headphone

  These values are the only differences, but they seem to change all the
  time, no matter whether a headphone is plugged in or not:
