start playing audio from a background task via AVAudioPlayer in Xcode

Question

I am trying to start playing a sound from a background task via an AVAudioPlayer that is instantiated then, so here\'s what I\'ve got.

For readability I cut out all user

Answer 1

If you need to start playing a sound in the background (without a trick such as keeping on playing at volume zero until you need the sound):

• Set Background mode Audio in your p.list;
• Set AudioSession category to AVAudioSessionCategoryPlayback
• Set AudioSession to active
• When your backgrounded app becomes running, start a background task before playing the sound (apparently when the remaining background time is less than 10 seconds, the sound is not played)

This now works for me.
