The new audio engine of Cocos2d-x is now available for the Android, iOS, the Mac OS, and the win-32 platforms. It is able to reproduce up to 24 simultaneous sounds on the Android platform; this number may change depending on the platform.

Therefore, the framework has only one setVolume method in contrast to CocosDenshion, which has two methods—setBackgroundMusicVolume and the setEffectsVolume.
