speaker issue after update

Hi Shahzadshah1,

Thanks for posting in Apple Support Communities.

We understand that your speaker is not working. To address the issue with no sound from your speaker, try using your speaker with various apps to determine whether the issue is within a specific app. If this affects a specific app, quit and relaunch the app, update it, delete and download the app.

If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open

If this affects multiple apps and sounds, check to see if Focus is enabled in Settings > Focus.

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.

You can find these steps and more in If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker.

Regards.
