Sounds stop working after using mute switch on iPhone 6
After using the mute switch on my iPhone 6, (I've switched it back to the un-muted position) nearly all the sounds stop working.
The ringer works normally, but, text, email, key click, lock screen, etc all stop working and do not produce any sounds until I reboot the phone.
This happens every time I use the mute switch to silence the phone for those times that I need to do so.
I am on 8.1.2 and am on Sprint iPhone 6.
Any suggestions would be appreciated.
