Please do not top post on this M/L.

As Alex suggested check that you have built your audio drivers as modules.  
Then run 'alsactl init' to initialise your card and unmute it.

Run 'lspci -k -nn' and check the vendor and product IDs shown in [square 
brackets].  Then Google for the right drivers and make sure they have been 
enabled as modules in your current kernel.

They were probably not compiled as modules?  ;-)

Try:

modprobe -r snd_hda_intel
modprobe -v snd_hda_intel

but if you get no output, then they were not built as modules in your kernel.
