It turns out that there is an option with only notifications? There is no way to ask the user to somehow allow this?

I need to turn on "AVAudioPlayer", what if I just turn on the audio in the background without sound so that the application does not block, and after 4 hours I turn on the sound? Is it even possible? Will such an application be missed?

I just need to start "AVAudioplayer" after 4 hours of delay. I understand that this is only possible through a "notification", which greatly complicates my development...
