Help? sounds and VoiceOver won't play through iPhone 6S speaker

Hardware and Accessories

The weirdest thing is happening. My Voiceover or other sounds/music will not play through my iPhone ^S speaker. However, it does work fine with bluetooth headphones and a USB speaker doc. The sounds and voice over speech also plays through the built-in speaker just fine if I am adjusting ringtones, etc, so I know the speaker is still working. But when I get out of say the ringtone selection screen and go back to the home page, nothing speaks.

Oh, I am using iOS V13.

Any thoughts on how to fix this? It's driving me crazy!!!
