Rip Wii disc audio?

Not sure if this is in the right section but cant really find anywhere more suited to post. I just wanted to know if it is possible to extract audio from a Wii game disc?

Why not if you can access the disc/content?!

But I cannot find any software anywhere to access the content. The disc wont even read in my PC and as far as I know the discs read backwards. Dont suppose anyone would know of any software, Ive looked everywhere but cant find anything.
