Probably worth running alsamixer just to check it's not as simple as 
everything being muted before you look deeper for the cause of your problems. 
If not, you'll want to unmute everything after completing the steps to make 
it work.

You'll want to check your kernel compile options to make sure you're compiling 
your sound drivers (preferably as modules), you'll also find that between 
kernel 2.4 and 2.6 there is a change from OSS to ALSA as the primary sound 
architecture.

www.alsa-project.org will be able to tell you what you'll need to know.

You'll want to add a line similar to this to your modprobe.conf file.

alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx 
&& /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1 
|| : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx

The extra lines will load and save the mixer settings for ALSA, the above has 
been taken from my modprobe.conf file.

You also might want to run alsamixer and just check that your sound isn't just 
muted. After the above steps you will still need to unmute your sound card 
anyhow.
