How to fix sound not working on iPhone 12 videos?

Hi twherman33,

You may need to ensure:

• The volume is turned up if needed
• You do not have "Mute" or "Silent mode" turned on
• Your speaker is working, and is activated. (eg: you hear music you play ok)

If you still need help:

Try these Apple Support articles:
