Taking ownership of the bug as I am also working on bug #1424147
Most probably we will move the playback of the sound out of the backend and expose a reusable ShutterSound QML component that apps can use if they want.

Title:
  It's not possible to disable the camera shutter sound in QML's Camera
  component

Bug description:
  The fact that the shutter sound when taking a camera picture is in the
  abstraction layer, forces that sound to be played every time a shot is
  taken with the QML Camera component.

  This means app developers cannot disable or override the shutter sound
  in their apps. One use case for this I encountered was while writing a
  QR code application that continuously takes shots and analyzes the
  image to scan a QR code. The fact that the shutter sound is played
  continuously prevents me from being able to use the QML camera
  component.

  <rsalveti> dpm: the sound file itself is available in the android system partition, and used by the app, let me find the code
  <rsalveti> qtubuntu-camera-0.3.3+13.10.20130919.2/src/aalimagecapturecontrol.cpp
   m_audioPlayer->setMedia(QUrl::fromLocalFile("/system/media/audio/ui/camera_click.ogg"));

  So after a conversation with rsalveti and jhodapp it seems that the
  shutter sound is only required by the camera app, but for some reason
  rather than put it in the camera app itself, it was added to the
  abstraction layer. Their suggestion was to file a bug to remove the
  sound from the abstraction layer and put it in the app, so that app
  developers can use the upstream QML component and be able to decide
  whether to play a sound and which one.
