+# DisableSounds
+
+Disable various system sounds.
+
+- Disable (regionally) forced camera sound
+- Disable shutter sound
+- Disable screenshot sound
+- Disable charging sound and vibration
+
+## Forced camera sound
+
+In some regions the camera sounds
+for shutter, start/stop recording and focus
+are enforced by law.
+This module tells the system that disabling the sounds
+is allowed.
+The system and apps will then show/enable their options
+for disabling camera/shutter sounds.
+This hook is always enabled, since allowing the option to appear,
+does not change the option by default.
+Be aware that it might be illegal to disable camera sounds in your country.
