Have a look at this link. This person describes getting sound going on this machine.
Read through the description. Go as far as you can. Post specific questions when you get to a step you do not understand. This is as close as you will get to a "step by step" set of instructions.
Here is another link with someone who has sound working. This is the sound module ( called a driver in windoze speak ).
Card Configuration options: rev=11 at 0x220, irq=5, dma=1
I would expect that module would be available from almost any distro.
