Thanks, Takashi. I tried installing the latest snapshot but wound up recompiling a bunch of stuff (which my box is not configured for)... Is there an easy way to download and install the latest snapshot?

Is there a way to fix the 0x0d widget? BIOS flash? laptop seems kind of new for that...

Try the hda-verb command first to check whether it's really an issue of 0x0d.

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
