I'm trying to make an app that plays audio when push is received, even while the ringer is silent.
I have the audio background mode enabled and the app works (usually) fine, but sometimes i get a mysterious 561015905 error.
The error is
AVAudioSession.ErrorCode.cannotStartPlaying
And docs indicate:
This error type can occur if the app’s Information property list doesn’t permit audio use.
It can also occur if the app is in the background and using a category that doesn’t allow background audio.https://developer.apple.com/documentation/avfoundation/avaudiosession/errorcode/cannotstartplaying
However, the audio mode is definitely enabled and the category is always playback that should allow background playing.
(this works 95-99% of times)
So, with intesnse testing i have found that once every 20-100 incoming pushes i get this error:
Error: Error Domain=NSOSStatusErrorDomain Code=561015905 "(null)"
Why?
