.wav files playback but .aiff files don't

Question

As a follow up to my (still unsolved) previous question, GUI event not triggering consistently, I've discovered another quirk. The code below creates and plays back a .wav file:

import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import javax.sound.sampled.AudioFileFormat;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.Mixer;
import javax.sound.sampled.SourceDataLine;
import javax.sound.sampled.TargetDataLine;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JRadioButton;

public class audioTest extends JFrame {

private static final long serialVersionUID = 1L;

AudioCapture audCap = new AudioCapture();

public static void main(String[] args) {
    new audioTest();
}

public audioTest() {

    layoutTransporButtons();
    getContentPane().setLayout(new FlowLayout());
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setSize(350, 100);
    setVisible(true);
}

public void layoutTransporButtons() {

    final JPanel guiButtonPanel = new JPanel();
    final JButton captureBtn = new JButton("Record");
    final JButton stopBtn = new JButton("Stop");
    final JButton playBtn = new JButton("Playback");
    guiButtonPanel.setLayout(new GridLayout());
    this.add(guiButtonPanel);
    captureBtn.setEnabled(true);
    stopBtn.setEnabled(false);
    playBtn.setEnabled(true);

    JRadioButton[] radioBtnArray;
    AudioFileFormat.Type[] fileTypes;

    // Register anonymous listeners
    captureBtn.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            captureBtn.setEnabled(false);
            stopBtn.setEnabled(true);
            playBtn.setEnabled(false);
            // Capture input data from the microphone
            audCap.captureAudio();
        }
    });
    guiButtonPanel.add(captureBtn);

            audCap.stopRecordAndPlayback = true;
            audCap.stopRecording();
        }
    });
    guiButtonPanel.add(stopBtn);

    playBtn.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            stopBtn.setEnabled(true);
            audCap.playAudio();
        }
    });
    guiButtonPanel.add(playBtn);
}

    }
 }
}

I tried changing the capture part to record an .aiff file instead, which works but playback is now silent. I can find the file and play via other means and it works fine but not in this program.

The lines I changed for recording the .aiff are:

// record as aiff
AudioFileFormat.Type fileType = AudioFileFormat.Type.AIFF;
// take user input file name and append file type
audioFile = new File(wavName + ".AIFF");

Anyone know why the .wav files playback via this code but .aiff files don't?

-EDIT- I also tried using .aif as the suffix but that didn't work either. And it occurred to me that it might have something to do with the files being stored as AIFF-C audio but I couldn't find anything further on this.
