    Is there someway to play synthesized audio when the app moves to background by pressing the home button?
    I am able to consistently reproduce this issue in a “Hello World” application that I have written for testing FliteController and openearsextras. I am happy to share this with in case anyone wants to try.

    I’ve tried all of the following:

    1.) Changed plist to indicate that app plays audio in background.
    2.) Added the following line. I don’t think this should make any difference.
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    3.) I’ve also tried changing the category of audio sesson to Playback in my app.

    AVAudioSession* sessionInst = [AVAudioSession sharedInstance];
    BOOL succ = [sessionInst setCategory:AVAudioSessionCategoryPlayback error:&error];
    if(error || !succ) {
    NSLog(@”Unable to set AVAudioSessionCategoryPlayback”);
    NSError* outError = nil;
    succ = [sessionInst setActive:YES error:&outError];
    if(outError || !succ) {
    NSLog(@”Unable to setActive”);
