Why isn’t my mouthpiece working

Hi Kasongolu,

Can you clarify for us more details on what's going on with your iPhone? We want to make sure we fully understand what you are encountering so that we can do our best to help and provide relevant next steps.

In the meantime until we get more details about your specific issue, if you’re unable to be heard when on a call or when using speakerphone (or not hearing sound when playing back audio in other apps), the steps in this article might be helpful to you: If the microphones on your iPhone aren't working - Apple Support

If you’re unable to hear others on a phone call, then you’ll want to follow the steps in this article as they are specific to that issue and may resolve it: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

We look forward to learning more details about what you're encountering.

Take care.
