Hello,
I developed our music app by using AVAudioEngine.
When I played music and called phone for interrupt test, i couldn't receive end interrupt notification.
I tried to solve this issue, and i found reason for this case.
When AVAudioEngineConfigurationChange notification issued, i restarted AVAudioEngine if user playing music.
But In iOS12.2 Beta, if AVAudioEngineConfigurationChange received before begin interrupt, End Interrupt not issued.
In other hand I did not restart AVAudioEngine, End Interrupt could be received.
I solved this issue that when AVAudioEngineConfigurationChange received, AVAudioEngine restarted after one second not stoped music.
But I want to solve completly. Could you help me?
