Facetime Notification Problem
When I close the lid on my Macbook Air and I am logged in to Skype I do not get a ring or any kind of notification when I receive an incoming call. I checked all the Settings on Macbook and in Skype and all Notifications are checked and Sound Effects seem to be checked correctly. I have to keep the lid open to get incoming calls from Skype and FaceTime too. When I close the lid while in a call it will drop the call.......It seems that all activity and Notifications stop when lid is closed. I hope someone can help.....Thank you.
MacBook Air, OS X El Capitan (10.11.3)
