iPhone 14 has stopped having sound when calling or receiving calls and alarm clock

Hi there gena268,

If you're not hearing sound as expected on your iPhone, start by checking your settings with this guidance:

1. If your device has a Ring/Silent switch, move the switch forward—toward the device's display—so that orange isn't showing. If you're using an iPad, you can also swipe down from the top-right corner to open Control Center and make sure that Silent Mode is off. 

2. Open Settings > Focus > Do Not Disturb and make sure that Do Not Disturb is off.

If you see that your iPhone isn't silenced and Do Not Disturb is turned off, follow these additional steps to see if they resolve the issue for you:

If you want to try more steps on your own

If you prefer, here are some more steps you can try on your own. After following these steps, you might still need to contact Apple Support to discuss service options.

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.

Also, make sure you've checked the volume on your iPhone, especially the ringer and alert volume:

1. Go to Settings .

2. Tap Sounds & Haptics (on supported models) or Sounds (on other iPhone models).
