There may be more than one thing wrong with that Mark 2. If it's freezing up on the audio driver initialization, then there might be something wrong with it internally.

Getting stuck on Bulding Music Databases might be related to the usual problems: disk drive trouble which often leads to file system corruption which often leads to database errors.

It's possible that the problem you're having is related to the CS4231A chip, can anyone else verify that this might cause the player to freeze during boot up on the audio driver message?

First step here should be to give us a proper boot log.
