What should I do if I have no sound after I upgrade ios7.1.2 to ipad air? How can we solve this problem?

 

First, we can try to restart the ipad air. If the problem cannot be solved, we can click General-restore in the ipad settings.

2. If the above problem persists, go to "settings ----- general purpose" on the ipad interface and select "mute" in "lock screen rotation" and "mute ", next, place the switch on the right, and then dial it up (note that you must keep the switch on top at last). Then, select "lock screen rotation" and exit the settings. Everything is OK.

Third, double-click the home key and we can see the playing status of the music. Let's manually control the volume to see if it works.

Fourth, if none of the above methods can solve your voice problems, we can try to restore the ipad to ios7.1.1.
