Stutter/little hangs in native (audioEngine related)

Im having little hangs or stuttering while i run “flappy birds with a sheep” example project in native or with the simulator (win32). BTW web browser runs smoothly.

To notice the issue, pay attention while scoring, there is a little hang or stutter while passing through a pair of pipes (kind of a mini-freezing/lag, idk how to describe it exactly) or when it plays sheep animations. Why this happens in native/simulator while in web browser is smooth?

It happens in my game too.

Using 1.0.2

EDIT: I did some testings and i think its sound related, i commented “cc.audioEngine.playEffect” lines and now apparently the hangs/stutters are gone. O.o

EDIT 2: Yeah, confirmed, it IS sound related, maybe audioEngine’s fault. Now, how do we solve this problem?
