How to turn off all volume on iphone 6?

I have the ringer on silent and the volume muted too, but i still get the sounds from when i get a text, call or notification from a game. How do i turn it all off without turning my phone off?

There's a little button above the volume button when you slide it and it's orange it knocks all your sound off slide it back and your sound will be back on

Flip that switch on the upper left side down.

You could turn the sounds for them off, but its odd that putting the phone in silent mode doesn't do that. When I use the silent switch every audio cue is cut.

Look for the Ring/Silent switch on the side of your iPhone. Tap the "Settings" app from the Home screen on your iPhone. Tap "Sounds." Turn off the option for vibrate mode. Since a vibrating iPhone can still make noise, consider sliding the "Vibrate On Ring" and "Vibrating on Silent" options to "Off." Then, tap the "Change With Buttons" option to "Off" if you want to ensure that the volume buttons don't accidentally turn the volume back on. Set the "Lock Sounds" slider to "Off." Turn the "Keyboard Clicks" slider to "Off" if you want to prevent the clicking sound when you type on your iPhone keyboard.
