You say you've tried everything, but just to make sure something hasn't been skipped:
- Ensure your iPhone's sound is turned on. Check the Ringer/Silent switch and the volume buttons.
- Verify that your iPhone is not in silent mode. Go to Settings > Sounds & Haptics > Ringer and Silence, and make sure the switch is not turned on.
- Confirm that your iPhone is not in DND mode. Go to Settings > Focus > Do Not Disturb, and make sure the switch is not turned on.
- Verify your Internet connection: For the Find My feature to work correctly, your iPhone must have an active Internet connection. Make sure your iPhone is connected to Wi-Fi or cellular data.
- Restart the iPhone: a restart can sometimes resolve temporary software glitches. Try restarting your iPhone and then see if the "Play Sound" feature works now.
- Reset All Settings: If the issue persists, consider resetting all settings on your iPhone. This will not erase your personal data (though you should always make a backup before doing anything major with your device just in case something goes amiss), but it will reset all settings to factory defaults. Go to Settings > General > Reset > Reset All Settings.
If none of that helps, you may need to contact Apple Support or visit an Apple Store or authorized Apple service center for further diagnosis.
Hope this helps. Regards.
