You figured it out yet? If not this will be pretty easy to fix. It should be a matter of building the alc 1220 driver into the kernel or getting a prebuilt kernel with the driver already configured and then
Code:
emerge -va alsa-utils
. Let me know if you still need help.

kurtiscobain,

Welcome to Gentoo.

Your alc 1220 is the CODEC. That's the analogue output part of your audio.
It also has an input part from one of the buses in your PC.
You need both parts and possibly some configuration.

What does
Code:
lspci -nnk
show. That should show all the input parts and the kernel driver in use, if one is loaded.

What is the content of /proc/asound/devices
That will tell if the kernel is set up correctly.

Lastly in quite common to have several sound cards. Which sound output do you want to be the default?
It may not be card0 devece0, which is what Alsa will use if you don't tell it differently.
