Bug Enable Custom Background Behaviors - NOT working (at least on iOS)

I am creating an audio player, so audio has to continue playing when player is in background.
But it does not work on iOS. (don´t know about Android yet)

I have selected "Audio, Airplay, PiP" in Player Settings
I have
Application.runInBackground = true;
in my script.

I am starting audioclips (1-3 minutes) via audiosource.Start()
Audio fades away after a few seconds in background and continues when app gets focused.

 

Answering my own thread!

I had to put these lines in the

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive:YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

into the xcode project
- (void)startUnityUIApplication*)application


@Unity GUYS!
Why can´t YOU put that there? Somebody came up with the solution 5 years ago!!!

 

Hey Kobald-Klaus,

Thanks for sharing this information. It helped me on a path to find a solution for playing my Unity Audio while the app is in the background.

I also wanted to allow my Unity Audio to mix with other audio apps (for instance with a music player like Spotify).

Here are the additions I added to UnityAppController.mm (Within the startUnity() method)
I left in the Unity generated code for reference.

EDIT:
Two other important steps (which have been mentioned - but I'll say again)....
1.) Import/include AVFoundation into your build in xCode (that's one I missed as well)
2.) In Unity PlayerSettings enable custom background modes and select the Audio option.

Code (CSharp):

1.  
2.  
3.     AVAudioSession* audioSession = [AVAudioSession sharedInstance];
4.     /*--------------------------------------------------*/
5.     /* GENERATED BY UNITY - COMMENTING-OUT....
6.     [audioSession setActive: YES error: nil];
7.     [audioSession addObserver: self forKeyPath: @"outputVolume" options: 0 context: nil];
8.     UnityUpdateMuteState([audioSession outputVolume] < 0.01f ? 1 : 0);
9.     */
10.     /*--------------------------------------------------*/
11.     /* THEN ADD IN THE FOLLOWING.... */
12.     [audioSession setCategory: AVAudioSessionCategoryPlayback
13.                         withOptions: AVAudioSessionCategoryOptionMixWithOthers
14.                         error: nil];
15.     [audioSession setActive: YES error: nil];
16.     [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

 

Do the iOS audio controls work for you using this method?

Thanks
