Wow, this is a blast from the past. That bug was probably one or two machines ago and I no longer have the hardware to test / reproduce it. This can be closed.

Based on Google searches I have fiddled with the snd-hda-intel options in /etc/modprobe.d/alsa-base.conf as follows: - Set model=thinkpad resulting in no sound through the headphone jack and the loss of the headphone playback connector in alsamixer. Unsurprisingly this results in no option to set or configure the analog headphone connector in the sound settings applet and/or pavucontrol. - Set model=generic with the same results as above. - Set model=auto which resulted in the appearance of the headphone connector (progress!) but I still get no sound from the headphones when I select the connector and/or mute the speakers through alsamixer. I also tried re-configuring the alsa-driver package to include verbose debugging support but ran into a whole lot of hassles (some of the source references smp_lock.h which is no more in kernel 3+, macro conflicts with system includes, etc.) when I tried to build it with module-assistant. I also tried to build it from the latest tarball from the alsa project with mixed results and ultimately no joy. Most problems of this kind I've seen tend to fall into 3 categories: (i) fixed by changing snd-hda-intel options, (ii) fixed through some sequence of random updates, (iii) sitting in silence. I'm hoping to be a bit more proactive. The output of alsa-info.sh is attached.
