Well... here we go then, the order I check things myself:

1) Drivers. According to your lspci output there, your kernel already
has the drivers for the card
--
Kernel driver in use: Intel ICH
--
and so that's covered.

2) Are the needed channels muted? Once you unmute them, assuming
alsa-utils is installed and the alsa service is started, the volumes
and muted/unmuted state should be saved between reboots (configurable
in /etc/conf.d/).

3) ... I rarely get this far.
