Choppy/Stuttering Sound - iOS 9.0.2

Is anyone else experiencing the sound stutter, crackling, for PS1 games? Really, all of the cores seem to be affected. If so, has anyone found a solution?

I have discovered one band-aid: if V-Sync is disabled under the video settings, the sound becomes clear. However, playing with V-Sync disabled is not ideal, as the FPS become unbearable. Running the most recent nightly build on my 6s Plus.
