What is the correct way to use AudioTrack in static mode?

I have an Android game in which I need to play short sounds. SoundPool crashes on dual-core phones , Mediaplayer has up to 200 ms + delay, OpenSL requires SDK 9+ (I support 1.5). So AudioTrack

This is what I tried. I create such AudioTrack objects.

protected AudioTrack createAudioTrack() {
    final int trackSize = 17408;
    return new AudioTrack(AudioManager.STREAM_MUSIC, 44100, AudioFormat.CHANNEL_CONFIGURATION_STEREO, AudioFormat.ENCODING_PCM_16BIT, trackSize, AudioTrack.MODE_STATIC);
}

Then I create a runnable for everyone in the game sound (about 8).

private static class SoundRunnable implements Runnable {

    private final AudioTrack sound;
    private final byte[] rawAudio;

    public SoundRunnable(final AudioTrack sound, final byte[] rawAudio){
        this.sound = sound;
        this.rawAudio = rawAudio;
        sound.write(rawAudio, 0, rawAudio.length);
    }

    @Override
    public void run() {
        playSound();
    }

    private synchronized void playSound() {
        switch (sound.getPlayState()) {
        case AudioTrack.PLAYSTATE_PAUSED:
            sound.stop();
            sound.reloadStaticData();
            sound.play();
        break;
        case AudioTrack.PLAYSTATE_PLAYING:
            sound.stop();
            sound.reloadStaticData();
            sound.play();
        break;
        case AudioTrack.PLAYSTATE_STOPPED:
            sound.reloadStaticData();
            sound.play();
        break;
        default:
            break;
        }
    }   

    public synchronized void release() {
        sound.release();
    }

}

Then, when I need to play the sound, I send it to ThreadPool.

private void playSound(final int soundToPlay) {
    final SoundRunnable soundRunnable = mediaPlayers.get(soundToPlay);
    if(soundRunnable != null){
        threadPool.execute(soundRunnable);
    }
}

The main problem I am facing is that the sounds are played twice the first time runnable is run. After that, every once in a while I can still get a double sound, but it works very well.
