Does lspci -k show it is using some sort of driver?  Mine for example 
shows this:

01:00.1 Audio device: nVidia Corporation Device 0be2 (rev a1)
         Subsystem: nVidia Corporation Device 069a
         Kernel driver in use: HDA Intel

If yours doesn't show a kernel driver in use, then it is likely a driver 
problem.  If it does show one, make sure it is the correct one.  I 
usually use this as a guide:

Just run the lspci -n command and paste it in there.  It works well.  If 
it shows it is loading the correct driver, something is muted somewhere 
or maybe it is as simple as you have the speakers plugged into the wrong 
plug.  I did that once on my first build.  I had two green plugs.  Sort 
of got the wrong one.  ;-)

I can't think of anything else at the moment.
