Using the same working .config (and make oldconfig make && make modules_install) from kernel 2.6.27-gentoo-r8, No sound is directed to the laptop speakers with any kernel after 2.6.27. Sound can be heard (with headphones) via the headphone jack, mic jack, output jack(front & back), and 5 surround sound jacks. http://forums.gentoo.org/viewtopic-t-763592.html is the list of everything that has been tried. Since that forum thread, I have also tried 2.6.27 (it works), 2.6.28-r5, 2.6.29-r5, 2.6.30 (gentoo and vanilla) it doesn't work. I have also tried various versions of the snd-hda-intel codecs with no apparent change.

I did not check the forum thread, but can you make sure no channels are muted by using alsamixer. Someone reported that channels were muted after each reboot.
I have checked, and nothing is muted. Using kernels newer then 2.6.28 cause them to be muted after each reboot, but un-muting does not change it only playing music through the connections and not the speakers.
Looks like upstream alsa has a report on this issue
this issue was fixed before gentoo-sources-2.6.30, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=679d92ed1403b6cf9a19aa42ec62b81cae1aa017
Except, I do have a front panel. Unless gentoo-sources / vanilla sources 2.6.29 - 2.6.30-gentoo-r5/2.6.30.5 do not have this fix, it doesn't actually fix the problem for my hardware (HP HDX 9300)
A bit more details are found in /usr/src/linux/Documentation/sound/alsa/HD-Audio.txt. read this maybe help
please make sure your channels aren't mute(alsamixer) if not, please try to reload module with 5stack-no-fp as parameter
5stack-no-fp kills sound from all the front jacks, as well as no sound from the speaker. Still allows sound from the rear jacks. 5stack Sound from all front and rear jacks, but not the speakers. 3stack kills all but 1 of the 3 rear jacks, but the front works, and no speaker. ref Sound from all front and rear jacks, but not the speakers ref-no-jd Sound from all front and rear jacks, but not the speakers auto Sound from all front and rear jacks, but not the speakers This is all with kernel 2.6.30-gentoo-r5
alsa team have some thing to add here ?
We'll follow the upstream bug.
As of kernel 2.6.32-gentoo, the sound works out of the speakers and out of the various ports. No extra options required.
