Hello,
Upon upgrading to 2.6.37, auto-muting-laptop-speakers-on-headphone-connect stopped working, and the headphone connector completely disappeared from alsamixer as well as the pulseaudio volume control panel. The headphone jack was still transmitting sound, though.
I bisected the problem, with 'good' being v2.6.36, and found the commit below as the first bad commit. Reverting it on v2.6.37 fixes the problem. I also tried the latest alsa-kernel master git tree, which had the same problem.
alsa-info when 'good':

alsa-info when 'bad':

Note: both were taken without X running, before pulseaudio came up.
================ 03642c9a444079aa13f0864383a8f9ca04bfd198 is the first bad commit commit 03642c9a444079aa13f0864383a8f9ca04bfd198 Author: Takashi Iwai tiwai@suse.de Date: Wed Sep 8 15:28:19 2010 +0200
ALSA: hda - Clear left-over hp_pins in snd_hda_parse_pin_def_config()
In snd_hda_parse_def_config(), some unused values may remain in hp_pins[] array during the headphone-reassignment workaround. This patch clears the unused array members.
