Keyboard clicks, lock sound, some game sounds stopped working
For reasons unknown, the sound on some but not all games have stopped working. Also noticed that lock sound and keyboard clicks are not working as well. Everything is set to ON. It was working earlier before I did some video... but video sound is working fine.
On the iPhone, there is a switch, but nothing on the iPad to unmute (even though it's not actually muted, since other sounds, including music, work).
I am baffled. Little help needed.
