Package: linux-image-2.6.18-3-686
Version: 2.6.18-8
After upgrading to package version 2.6.18-8, the headphone socket on
my laptop (Dell Lattitude D420) stopped working. The sound plays fine
through the speakers, but when plugging in headphones the speakers
continue to play the audio, while the headphones remain silent.
Reverting to version 2.6.18-7 fixes the problem.

Okay, it appears to be working correctly (version 2.6.18-8) after I
added a file /etc/modprobe.d/alsa-special containing:
options snd-hda-intel model=3stack
I guess that means that the alsa driver is just needs the PCI id for
my card to know how to set up the chip. I'll submit the id to that
alsa bug tracker.
Cheers,
Kevin.
