Streaming audio file from ram through ac97

hi all.  i'm trying to stream an audio file from ram into my ac97 codec but i don't know how i should approach this.  any hints or tips on how i should get started?  also, does anyone know what type of data the ac97 takes in?  i doubt it'll take in .wav files.  i'm considering converting the .wav file into raw data using matlab and using the xmd to write it to ram.  any suggests will be of much help.  thanks.
