Are any Alsa devs reading this list or do I need to post this elsewhere?
I've got a new Intel motherboard that was just recently released which
uses the new H55 chipset. The spec sheet says it's Intel HDA but I
don't think Alsa or the kernel is recognizing it, at least not
automatically. The kernel is 2.6.32-gentoo-r2 for now.
Is this a case of me doing something wrong in configuration or is it
possibly a PCI ID thing that's not updated as of yet?

So I suspect the PCI ID is 8086:3b56.
The kernel config turned it on:
firefly etc # cat /usr/src/linux/.config | grep HDA | grep INTEL
CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_CODEC_INTELHDMI=y
firefly etc #
I can modprobe the driver by hand:
firefly etc # modprobe snd-hda-intel
firefly etc # lsmod
