How to play a simple sound in IOS with adobe air on background

Apple is not allowing anymore to access the background for my app and I need to be able to play a simple sound in IOS with adobe air when the app is on background without using "audio" UIBackgroundModes.

If my app include the UIBackgroundModes "audio" the app is able to play a simple sound alert in background but if I removed the "audio" mode like apple requested the app is not able to play a sound anymore.

Anyone know how to play a simple sound in background on adobe air?
