This has been asked before, in some countries the sound is standard as it is something related to privacy.
On mine when you open the camera you tap the 3 dots then the crossed spanner then near the bottom it says turn sounds on or of however if you don't have these then this could be a country thing
I know @Thommo, I have the same on both Z1 and Z2,but on others it is not possible.
