Hey there TonyMan13,
Thanks for reaching out in Apple Support Communities. I understand you’re having issues with the audio from your Twitter app. I’ll be happy to help.
Force quit the Twitter app and restart your iPhone. See if this has any impact on the issue:

Restart your iPhone, iPad, or iPod touch
If that doesn’t help, delete the Twitter app from your iPhone, restart, and install the app back onto your iPhone. Test again and see if this resolves the issue.
If not, back up and update to iOS 13.1.2 to further isolate the issue:
