iPhone "[AVAudioSession sharedInstance] setActive" There is no sound in Unity after turning it off and on

Question

The currently used package will execute the following [[AVAudioSession sharedInstance] setActive: NO error: nil]; [[AVAudioSession sharedInstance] setActive: YES error: nil];

But the audio of AudioSource is gone. Go back to the iphone desktop and go to Unity. Sound is restored.

How to restore the sound without returning to the desktop?

Hello, I myself face this problem for the past 2 days, and after a lot of search i finally found something to fix this.

By using [[AVAudioSession sharedInstance] setActive: NO error: nil], you're stoping unity audio service from working.

But using [[AVAudioSession sharedInstance] setActive: YES error: nil] isn't enough to make it work again.

You have yo actually "reset" the unity audio service to reinitialize everything.

And you can actually do that very easily by using AudioSettings.Reset inside C# code.

However, it reset also every AudioSource present in your scene.
