As Rex said, this is not a pulseaudio issue.  Alsa isn't being detected 
properly.
It is loading a driver module, but looks like the wrong one.

A driver module is being loaded, snd_hda_intel.

It looks like it is the wrong driver module.  You probably need to add 
options
like 3stack 6stack etc.    Your card is defaulting to 3stack so you 
probably want
to try other options. 

Add them in the /etc/modprobe.d/sound file as lines like:
options snd_hda_intel model=mbp3

This is necessary because the hda_intel chip can be wired in many different
ways, so of course it is wired in many different ways.  Alsa has a hard time
differentiating them in some cases, and gets it wrong.  The above gives it a 
hint to use the correct one.

Could you also run alsa-info.sh with --no-upload option and attach
the generated file for a more comprehensive information?
The script is found at  http://www.alsa-project.org/alsa-info.sh
