Picking up gibberish.

[sleep9]

AudioQueueStart was returning OSStatus -50.

Adding the following code to prepareRealtime solves the issue

AVAudioSession * session = [AVAudioSession sharedInstance];

    if (!session) printf("ERROR INITIALIZING AUDIO SESSION! \n");
    else{
[session setCategory:AVAudioSessionCategoryPlayAndRecord error:&nsError];
     
        [session setActive:YES error:&nsError];
    }

However now when I run the application I get a constant stream of gibberish detection. Any ideas?
Im not sure if Its hallucinating or the buffer is polluted with data from somewhere else.
