you could also try using FAR manager and edit the customization.xml found in your mobile's File System folder under the directory \tpa\preset\custom by adding these lines before the </customization> tag:
Code:
<camera>
<suppress-camera-sound>true</suppress-camera-sound>
</camera>
This enables camera's to supress the shutter sound when you switch to silent mode on your phone.
