What is it you are using to test sound?

It does not look like alsa is running. Have you configured alsa as per
the instructions in the web site? Is alsa starting correctly? (for
example, do you have a directory named "/proc/asound"?). What are the
contents of your /etc/modules.conf? What kernel modules do you have
loaded? ("/sbin/lsmod")
