Well, for a start, technically, what do you mean by BGM? Is it AdLib, MIDI, what?
Also, presuming there is SoundBlaster support in this game, is it SoundBlaster 16? Pro? Just basic SoundBlaster?
Taking a wild guess that the "BGM" is FM (AdLib or SoundBlaster), you might want to change VDMSound default SoundBlaster16 setting down to a basic SoundBlaster (1.0x). The SB16 and some "Pro" cards used an OPL3 FM-audio chip and the game might be attempting to use OPL3. Choosing a basic SoundBlaster should force it use OPL2.
