Make Siri Ding Again on Pressing Home Button So according to this Apple support article, Siri doesn't make that bell sound after holding the Home button to launch it on iPhones with iOS 9 or later. Instead, it vibrates.


  On your iPad or iPod touch, Siri will chime when it's time to ask a question. If you have an iPhone with iOS 9 or later, Siri will vibrate instead. You'll only hear the chime on your iPhone with iOS 9 or later when you're using headphones.
  Siri will also chime when you use "Hey Siri" on a device with iOS 9.


That's really unfortunate because I really liked that ding.

Does anyone know if there's a way to make Siri play the "ding" sound again without headphones or Hey Siri? (Aside from jailbreaking)
The only solution I have found with ios 9 is to go to Settings > Accessibility, and turn Vibration off. Extra caveats can be found in the source link.
