Skype aucun son pour les appels entrants

Google translation.

No sound for incoming calls on Skype

Make sure your iPad isn't muted.

Check to see if Skype has a in-app mute and if it's on.

Try a reset. Press and hold both the home and power buttons until the Apple logo appears. Release both buttons. Wait until your iPad starts on it's own.

If still no sound delete and re-install the Skype app.
