How to Disable the Camera Shutter Sound on Stock Android
Devices like the Nexus 5X and the Pixel run stock versions of Android. Stock Android doesn’t have a camera setting for disabling the camera shutter sound. Instead, you will have to turn your notifications/alerts profile to silent, do not disturb or vibrate. This can be done using the volume keys on the side of your device that act as master volume controls. Newer devices which run near-stock Android tend to use the same method, so newer devices tend to be more intuitive.
