BoF4 has no CDDA audio. Iori's SPU (and presumably Eternal SPU) should play all the ADPCM music in the game fine. The broken sound clips, as well as a couple streamed musical pieces that won't work, are CDXA audio, and ePSXe has incomplete CDXA audio emulation. If you really want to hear them use PSMPlay to play the XA tracks.
