The problem was that your BIOS didn't set the correct default pin configuration. The driver doesn't know which pin should be used for the speaker output, as a consequence, it's set as INPUT. Now you set it OUTPUT manually by hda-verb, and (fortunately) the route to that pin was alive even though it wasn't declared, you get the speaker output now.

The next step is to implement a proper pin-config to override by the driver. This won't be much work, but hey, wait for a while.

(Or, did Herton already work on that?)

thanks,

Takashi

Takashi, I was able to build hda-verb and when I executed the command
below, it responded with:
nid=0xd, verb=0x707, param=0x40
value=0x0

    Did you try the latest alsa-driver snapshot?

    If it still doesn't work, I guess this is a BIOS problem.
    The other HP dv laptops show the widget 0x0d as the speaker while
    yours is unused.

    Try to run:
           hda-verb /dev/snd/hwC0D0 0x0d SET_PIN_WID 0x40
