Q: iMessages, text messages nor sound works with be download

Hey AMT14,

Thanks for the question. I understand you are experiencing audio issues with your iPhone 4s. First, lets make sure the Ring/Silent switch is not toggled, and works properly:

iOS: Understanding sounds, ringtones, and alerts

If you have not already done so, try restarting and resetting your iPhone:

iOS: Turning off and on (restarting) and resetting

If your issue persists, we'll need to isolate it further by completing a software restore with iTunes. Please be sure to backup your iPhone first.

Choosing an iOS backup method (Should I use iTunes or iCloud to back up my iOS device?)
