less /var/log/syslog
less /etc/modprobe.d/alsa-base.conf

also check if this help: http://antix.freeforums.org/no-audio-intel-n10-ich-7-hd-audio-t2564.html ==> related to this post http://ubuntuforums.org/showthread.php?t=1043568&highlight=intel+sound+database
(this post is pretty old so keep in mind that the right path to alsa in the modules folder now is:

Use the alsa-info-script to provide detailed information.
Run this command in a terminal:

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh
Choose the upload option and provide a link for the output.

Is your volume turned up? open a terminal and type the command: alsamixer (when the pages appears use your directional keys to navigate around), increasing the volume and such, also hit F6 while you have the alsamixer page still opened and choose your other device if there is one and make sure everything is enabled and volume is set..
