earpiece not working after ios updated to ios16

Greetings arudrase2,

Thanks for posting in the Apple Support Communities.

We understand you've noticed a concern with an earpiece since updating to iOS 16; however, we may need additional clarification if the following information doesn't help out.

If you're referring to the earpiece speaker used when making phone calls, try restarting your iPhone to see if that clears this up. If that doesn't help, give the following steps a try: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

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.

If you're referring to a pair of headphones, check out the steps of the following resource instead: If your headphones don't work with your iPhone, iPad, or iPod touch - Apple Support

Should you need more assistance, clarify for us which earpiece you're referring to. In addition, let us know which steps you've tried along with the results.

Have a great day!
