When is AVAudioSessionSilenceSecondaryAudioHintNotification triggered?

Quoted from Xcode doc,

AVAudioSessionSilenceSecondaryAudioHintNotification Posted on the main thread when the primary audio from other applications starts and stops.

Subscribe to this notification to ensure that your app is notified when optional secondary audio muting should begin or end.

However, when my app's audio is playing, and I press the remote-control to start playing music from the Music app. This notification is not triggered in my observer callback. I believe the registration was successful.

Am I having the wrong expectation? Is it supposed to be triggered in a different scenario? Any examples?

You need to set your AVAudioSession Category to AVAudioSessionCategoryAmbient, then your app will allow background apps (such as music or podcasts) to play. If you set it to AVAudioSessionCategorySoloAmbient then it will not accept background music

You can do it like this:

NSError *categoryError = nil;
if ([[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&categoryError]) {
    printf("Setting AVAudioSession CategoryAmbient Succeeded\n");
} else {
    printf("Setting AVAudioSession CategoryAmbient Failed\n");
}
