Android sound issues - not consistent sound performance

Hi

I’m new to cocos2dx and Android, I’m trying to convert my cocos2d project from IOS to android.
I’m having problems with the sound on the Android device/emulator.
The sound doesn’t plays all the time.
I’ve tried to preloaded it and that helps a little but still the sound doesn’t plays each time it suppose to.
I’m using OGG files as recommended after trying wav and mp3.
I also read other similar messages but didn’t find any solution.

So if anyone knows anything please share.

Thanks
