[Q] Camera sound on GT-N7000

Can anyone suggest why I no longer get the camera shutter sound? It doesn't work with the stock camera app (I mean the one that comes with the ROM I'm using) or third party ones. I can't find any settings disabled.

I recently had a repair done at Samsung which involved replacing the motherboard. I didn't test every single setting and function when I got it back so am tempted to assume it is related to the repair but I could be wrong.

The camera is rooted and I'm using the Ultimate XXLT4 JB 4.1.2 v6

Thanks in advance
