Answer 1

include your playSoundFile call in the below, this should always run it in main thread

dispatch_async(dispatch_get_main_queue(), ^{

});

add this if to your - (void) playSoundFile to check if player is created, if not, then create it

if(!_player) {
    _player = [[AVQueuePlayer alloc] init];
}
