Panic when sink ends - Githubissues

Behavior: When an audio sink ends, the thread it is running off panics and terminates Code Used: ```rust pub fn play(name: &String) { let (_stream, stream_handle) = OutputStream::try_default().unwrap(); let sink = Sink::try_new(&stream_handle).unwrap();

let file = BufReader::new(File::open(name).unwrap());
// Add a dummy source of the sake of the example.
let source = Decoder::new(file).unwrap();
sink.append(source);

// The sound plays in a separate thread. This call will block the current thread until the sink
// has finished playing all its queued sounds.
// The point of the loop is to play till the thread is terminated by the OS, restarting the song if needed.
loop {
    while !sink.empty() {
        sink.play();
    }
    sink.append(Decoder::new(BufReader::new(File::open(name).unwrap())).unwrap());
    println!("here");
}

}

Note that it never reaches here. The same error has occurred while using `sink.sleep_until_end();` instead of the loop.
