Handling audio playback in app-background mode

[Mark Anderson]

Hi everyone,

Question regarding the playback of audio when a user didEnterBackground:

How is this handled in ObjectAL? Is there a way to continue playback of audio when the user didEnterBackground AND/OR if the user turns the phone off? I.e similar behavior to iPod playback/ music playlist app?

Thanks!

Mark

Hi all,

I'm looking for the exact same thing, but with no luck.

Has anybody found a way to do app-background audio with ObjectAL ?

(In my case, I'm trying to listen to inter-app MIDI messages and play audio files while in background)

Thanks...

I realize that I'm replying to a old post, but I just ran into the same issue myself and this is what comes up when I search for this. It turns out to be quite simple, but hard to figure out for me.

To get background audio you need to do two things:

1) In your plist (in Xcode, choose Target->Capabilities), enable the BackgroundMode flag for "Audio and Airplay"

2) before you start using audio, do this:

[OALAudioSession sharedInstance].audioSessionCategory = AVAudioSessionCategoryPlayback;

(you may want to look at some of the other AVAudioSessionCategories, there might be a better fit).

I'm not sure if there is another more low-level background mode, but this was enough for me to get audio to continue when the phone is locked or if you're switching to other apps.
