If you updated your kernel in Jaunty, you will have to re-install the ALSA modules with another round of `sudo make install`. Also, see my note above that I have to move the "Master" channel up until sound finally crackles on for the rest of the system, including the headphones.
Note that this patch still doesn't work perfectly for me, since apparently my soundcard has "a different PIN assignment"; e.g., I'm getting noise in the headphones and my internal mic doesn't work.
