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.

if your Dell Studio 1458 have dual HP Out at Ext Right - node 0x19 and 0x1b , the latest driver seem put them into line_out instead of hp_outs
hda_codec: ALC665: BIOS auto-probing. autoconfig: line_outs=2 (0x19/0x1b/0x0/0x0/0x0) speaker_outs=1 (0x15/0x0/0x0/0x0/0x0) hp_outs=0 (0x0/0x0/0x0/0x0/0x0) mono: mono_out=0x0 inputs: Internal Mic=0x12 Mic=0x1a
