How do I activate sound for incoming and sent mail in iOS7? If I go to Settings I see there is a check mark next to Ding, but I don't hear a Ding when I receive an email like I do on an OSX computer. Same situation with Sent Mail (I have the Sound Volume set to medium and the Sound on my iPad Air definately works. I looked in the iPad manual under Mail for Sound help and there was no information given about how to activate sound for incoming and sent mail.
