Current implementation of Camera service plays the camera shutter sound over the ALARM stream so that it cannot be muted by silent mode in order to comply to some country specific requirement. A recent change made it possible for the user to mute the ALARM stream thus making this stream not suitable any more for the camera shutter sound.
The fix consists in creating a new stream type only accessible by native code and that cannot be muted and use it to play camera sounds.
