Q: Why is my iPhone not giving me sound notifications when it is on loud and the sound works?

Hi floridagirl0496,

Check the Ring/Silent switch above the volume buttons. If you can see orange, it's set to silent. Turn it off. Also check to see if Do Not Disturb is on. Go to Settings > Do Not Disturb, and make sure Manual is set to Off. If it's on, it will silence any incoming calls or messages when the screen is off. If it's still not working, this article has some more steps to help resolve it:

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support
