Although it may not help, you can overcome the DOS path problem by using the 'dot' to navigate from the current directory. e.g ".//Sounds//my_sound.wav". A double dot will take you up one level e.g "..//Work//Sounds//my_sound.wav"

From your reply it appears you may have set up a special project directory. Have you tried moving your files to the "Work" directory and rebuilding? The soundfile code seems a bit picky in its path definitions.
