That pin config actually looks strange.  It defines 4 "speaker"
outputs.  The autocfg routine in hda-intel driver switches these
speaker outputs to line-outs (just for compatibility issue).  That's
why you don't see any speaker there.

The patch below is a quick fix to change the jack types for 3
outputs.  Give it a try.

Now more questions:

- Does your machine have 3 output jacks in addition to HP?

- What is the content of /proc/asound/card0/codec#* when you load the
  driver with model=auto?  After setting it, reboot so that BIOS
  resets the configuration.

- Show both codec#* files for model=auto and without model option.


thanks,

Takashi
