Hi 20Oceanside20,

Thank you for contacting Apple Support Communities. Based on what you stated, it seems like you are not able to hear unless the iPhone is using the speaker. We would recommend you use this article to help troubleshoot the issue.

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