It seems like nobody knows about how to rip the music of CD-i discs, there has also been no answer on a forum post about the specifications of CD-i audio music as well. It looks like more people are interested in it (I'd love to hear the Litil Divil soundtrack again), but the knowledge isn't there. CD-i Fan responds: "here is currently no single tool to do this. It is possible to extract the music files from the CD using e.g. IsoBuster, but they need some massaging (selecting the right channel and/or stripping headers) before the data is in "pure" ADPCM format. The "pure" ADPCM format is identical to the one used with CD-ROM XA and there are some tools out there to decode it; I think ffmpeg is one of them. This assumes that the music is stored on the disc in "native" CD-i format; if not actual runtime grabbing (using either a CD-i emulator or a hardware player) is the only way. Many titles store the sound effects in encoded form, for example. A future project of mine is to create a standalone "CD-i File Player" that would provide most of the above with a graphical interface like IsoBuster; most of the support code is already in CD-i Emulator..."
What I always did is using my Minidisc recorder to record the audio (analog). It works perfect, although I remember playing Litil Divil I had to watch out little Mutt didn't fall asleep because he'd start snoring and disturbing the background music
