Resident evil remake GC sounds

Hi,

Im just looking for some help for ripping this game. the thing is, ive just ripped the iso from my disc of this game, and i wanted to use the sounds (gunshots etc) to mod resident evil 4 for PC.

The thing is, ive found lots of sound files in the game disc, and they are all in a .SND format (or AU format as windows recognises them)

now these should be able to be played in windows media player right? problem is when i try to, it just gives a slight high frequency noise and thats it.

I was just wondering, are there any programs out there for gamecube development and hacking etc that would be able to do the job?

Thanks for your help on this
