Thank you very much for your quick response. I have actually made
progress. Using hda_analyzer, I have changed the pin ctls to be OUT
and HP, instead of just OUT. I read from the Intel doc that setting a
pin to HP will enable an output amplifier. True enough, this gave a
boost to the volume, it is close enough to the soundblaster's volume.

Now I am back to trying to figure out how to set the HP in the
user_pin_configs hex value. Do you have any documentation references
on how to set the hex value for user_pin_configs? I have tried to
Google for it, and also tried to find it from Intel's website, but to
no avail.
