I have seen your question is yet unanswered so I am here to answer it.
I have also finished the entire game, and bought its extra chapters and volumes. As an experienced game collector and developer, I can safely say that the soundtracks are unobtainable. Unless its sound reel is uploaded to the public, by the producer, Electronic Arts Games; short known as "EA Games".
If you have further uncertainty, please contact me through davennport at yahoo. and I'll be glad to inform and clarify your questions.
