Seems like this game has CDDA audio, try this method:
Make an ISO image of the game (i suggest that you make one with alcohol 120%).
Use Mooby2 cd disk image driver (cd-rom plugin) and configure it like this:
- Repeat all CDDA tracks.
- Enable subchannel data.
- CDDA Volume bar to the maximum (value 1.00).
After that go to File - Run CDROM (not Run -> ISO) and browse to the image you made earlier.
The sound should work now, if not make sure that 3 top boxes in the sound config are checked.
Btw: You can download plugin
here (the name is CDR Mooby).
