Кажется, я ответил на свой вопрос.
После дальнейших исследований, использование SourceDataLine
- это путь, который блокируется, когда вы дадите ему достаточно для работы.
Извинения за отсутствие надлежащего Javadoc.
class SoundPlayer
{
// plays an InputStream for a given number of samples, length
public static void play(InputStream stream, float sampleRate, int sampleSize, int length) throws LineUnavailableException
{
// you can specify whatever format you want...I just don't need much flexibility here
AudioFormat format = new AudioFormat(sampleRate, sampleSize, 1, false, true);
AudioInputStream audioStream = new AudioInputStream(stream, format, length);
Clip clip = AudioSystem.getClip();
clip.open(audioStream);
clip.start();
}

line.start();
// if you wanted to block, you could just run the loop in here
