iPhone 11 has No Sound On Live Photo

Hi stasha161,

Thanks for contacting Apple Support Communities!

We understand that you don't hear any sound from your Live Photos taken with your iPhone.

Since you've already ensured that you have your silent / ring switch enabled to ring, you can also edit the photo to ensure that the Live Photo isn't muted. When you edit your Live Photo, you can simply tap the speaker icon to enable or disable the sound as outlined here: Take and edit Live Photos - Apple Support

"How to edit Live Photos

1. Open the Photos app and tap the Albums tab.
2. Go to Live Photos under Media Types. 
3. Tap the Live Photo that you want to edit.
4. Tap Edit, then make your adjustments.
5. Tap Done."

We hope this helps you.

Cheers!
