Maybe I should add an ncurses interface ;-)
Anyway, if it's easier for you to read the HDA spec than upgrading your
laptop, you can use the kernel interfaces directly using a "firmware
patch" file or reconfigure sysfs. This is what hda-jack-retask uses.
The documentation for these interfaces are at
http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt - see
the "HD-Audio Reconfiguration" and "Early Patching" sections.
Or a compromise; boot up a live-CD of a newer distro, create the
firmware file with hda-jack-retask, then copy the result back to your
current distro setup.
