Inability to hear sound from ear speaker?

Hello victor5168.

Thank you for using Apple Support Communities. It sounds like you're experiencing issues not able to hear from your receiver speaker. If so, we'd like to help you out. We also noticed that you're already coming from the following resource: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

Did you already attempt the following steps below?

1.) Remove all screen protectors, films, or cases from your device.

2.)Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty.

3.) If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.

4.) Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.

5.) If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location.

If so, we recommend that you reach out to Apple Support for assistance. They might have to get your device physically evaluated to make sure everything is properly working. Just in case, you can use the following link to reach them: Get Support - Apple

Thank you for using Apple Support Communities. Best of luck.
