[Android] Audio Crackles in every game with full speed

[astroprogs]

Hi guys!
I'm having this very weird issue with the Android version.
The Audio crackles in every game whether the game is running at full speed or not.
No matter how simple what PPSSPP renders it's always crackling, title screens ,options menus, etc.

I have a Galaxy S3(OC'd at 1.6ghz), and I'm using the latest rev build with the default setting.
Different settings have been tested, like minimizing the visual fidelity and increasing audio latency, with no apparent improvements whatsoever(the games were running at 30/30 fps in the first place so) .
The same issue persists on other multiple Galaxy devices BTW. The Audio still crackles everywhere.

Games i Tested:
Persona 3 Portable
Fate/Unlimited Codes
Black Rock Shooter
K-On
Code Geass Lost Colors (which is a visual novel, so it's definitely not a speed thing)
