Audio delay?

[Lilsis8765]

Umm, so, I just got this emulator recently and I decided to play the Corpse Party games on it. Corpse Party one worked great, but Corpse Party Book of Shadows has an audio delay. I don't know how to fix this and it's really annoying as the game relies on voice acting and sound effects to help since the game has so many cutscenes. If anyone knows how to fix this, it would be highly appreciated.
