i hope my assumption that the wm8731 chip is the one on the DE2, as it was the one listed in the documentation that came with the board.

it included:

wm8731.c

wm8731.h

i noticed that there were functions such as wm8731_init() that register the device with the kernel, i guess whats left to ask is how do i use these files and if any additional porting is needed.

and once registered how will i be able to place the audio data on the FIFO for processing and playing?
