a new lead:

turns out that i have two sound cards in my laptop. one for the internal speakers, one for the external connections (mic, line-out). ubuntu must have recognized only one of them. the laptop is HP Pavillion dv6186ea (dv6000 series).

any one has any kind of idea what to do with this new information?
I am currently running the most recent release candidate alsa driver. Alsa mixer picks up the following services:
headphone;
pcm;
pcm2;
mic bypass;
mic gain;
capture;
speaker.

This is how it manages the "two cards" you speak of.

See also my how to for my HP dv2000. It "might" help.
