Как воспроизвести звук в JAVA?

AudioFormat audioFormat = new AudioFormat(8000, 16, 1, true, false);
    private TargetDataLine targetDataLine;
    private SourceDataLine sourceDataLine;
    private Object sourceDataLineMutex;
    private DataLine.Info targetInfo;
    private DataLine.Info sourceInfo;
...
AccessController.doPrivileged(
            new PrivilegedAction<Void>() {

                @Override
                public Void run() {
                    try {
                        targetDataLine = (TargetDataLine) AudioSystem.getLine(targetInfo);
                        targetDataLine.open(audioFormat);
                    } catch (LineUnavailableException e) {
                        logger.error("target line unavailable", e);
                        return null;
                    } catch (SecurityException e) {
                        logger.error("security exception", e);
                        return null;
                    } catch (Throwable t) {
                        logger.error("throwable " + t.getMessage());
                        return null;
                    }
                    targetDataLine.start();
                    synchronized (sourceDataLineMutex) {
                        try {
                            sourceDataLine = (SourceDataLine) AudioSystem.getLine(sourceInfo);
                            sourceDataLine.open(audioFormat);
                        } catch (LineUnavailableException e) {
                            logger.error("source line unavailable", e);
                            return null;
                        }
                        sourceDataLine.start();
                    }
                    return null;
                }
        });

Воспроизведение аудио работает нормально, но при попытке воспроизвести еще один файл получаю ексепшн ( targetDataLine.open(audioFormat); - в этом месте):
