Lemme put it this way, the SPUAsync doesn't sync the sound at all. I've tried all three modes and there's no difference whatsoever. Take the cursor sound in FFVII, VIII, and IX; it sounds like the sound Zsnes has in Square Enix games: it's crap. People on the internet claim that "they have syncronized sound", which I think is BS, IMO. I do get sound, but it sucks. Only if SPUAsync actually synched the sound effects/music, I'd be happy. BTW, the weird thing is ePSXe supports that feature. Here are sound clips attached to this post:
