This game was tested with r3732. The audio seems to stutter/crackle at the Title Screen or as the user is about to load their SAVEDATA. A sharp sound can be heard when the user is browsing the Options (be idle at this screen and the sound will pop up once in a while) or other parts of the Menu.
A problem that still lingers after many builds is the emulator freezing because too many NOP instructions are being executed. This error appears most often when one finishes a battle (character is flashing a couple of times before game freezes), but can probably be triggered in other ways as well.
Here is a video of some of the issues that occur in the game (JPCSP r3732 64-bit):
