Ainol Aurora II Sound Stuttering

[IDSG]

Im testing this emulator, im using CM9 for aurora II, im using the latest version, the games are CTR And Castlevania, both works at fullspeed (60fps CTR and 50fps Castlevania), the sounds stutters in both games, i checked spu sync but didn't help, im doing something wrong?

No, spusync and fullspeed are right. Make sure the fps are constant.

FPS ara constant all the game, even at menus are problems with the sound, dont know what to do

[IDSG]

Opengl wont work with mali 400 devices on the latest version (0.11.45) so i can't test that, im using a .bin file in both games

[IDSG]

is the same running from cue or bin, the sound is bad always, even in the sony bios logo, i dont know what can be, the games runs perfectly at full speed.

EDIT: Did some tests

the sounds works good if i turn off spusync and hardware acceleration, so something is incompatible with this tablet/rom
