You may wish to try the non-kernel alsa drivers. I have an Intel HDA soundcard
in my laptop and the sound was poor and quiet when using the kernel modules but
much better when using the alsa drivers in portage.
I believe it has been suggested before that the seperate alsa modules may be
more up to date. Can't hurt to give them a try I guess.
I did just notice this in dmesg:
ALSA
/var/tmp/portage/media-sound/alsa-driver-1.0.14_rc2_p3234/work/alsa-driver-1.0.14rc2_p3234/pci/ac97/ac97_codec.c:2043:

I'm using ALSA_CARDS="ali5451" based on lspci:
