Duck Other Sounds when a sound is playing

[jvwelzen]

Is it possible to duck other sounds when playing a task audio or pop audio

if I change this code the sound is ducked but it's not restored to the original sound volume

- (void)pluginInitialize
{
    self.fadeMusic = NO;

    AudioSessionInitialize(NULL, NULL, nil , nil);
    AVAudioSession *session = [AVAudioSession sharedInstance];
    // we activate the audio session after the options to mix with others is set
    [session setActive: NO error: nil];
    NSError *setCategoryError = nil;

    // Allows the application to duck the sound from other apps.
    if (![session setCategory:AVAudioSessionCategoryPlayback
                  withOptions:AVAudioSessionCategoryOptionDuckOthers
                        error:&setCategoryError]) {

        NSLog (@"Error setting audio session category.");
        return;
    }

    [session setActive: YES error: nil];
}

I think that the session have to be set to not active but until then no success

If I try to set the session to non active when a sound stops I receive compile errors in phonegap build

I have found a solution to duck the other sounds on ios

- (void)pluginInitialize
{
    self.fadeMusic = NO;

    AVAudioSession *session = [AVAudioSession sharedInstance];
    // we activate the audio session after the options to mix with others is set
    [session setActive: NO error: nil];
    NSError *setCategoryError = nil;

    // Allows the application to mix its audio with audio from other apps.
    if (![session setCategory:AVAudioSessionCategoryAmbient
                  withOptions:AVAudioSessionCategoryOptionMixWithOthers
                        error:&setCategoryError]) {

        NSLog (@"Error setting audio session category.");
        return;
    }
    
}

you wil need a timeout on the stop command to restore the original sound

            setTimeout(function(){
            audio.stop('pstt1');
            }, 2000);
