MediaPlayer : Should have subtitle controller already set: KitKat

Question

I am having an odd issue where my audio file sometimes plays and sometimes does not play. The catch is that when it decides to not play, the DDMS gives me an:

E/MediaPlayer﹕ Should have subtitle controller already set

Because this is one-to-one with the music not playing, I have determined that this is probably the issue...

If the music is not playing and I hit the volume button it begins to play. If I wait about 30 seconds of no-play, it begins to start again (not looping).

Whats going on here? I am on KitKat using

        player = new MediaPlayer();
        AssetFileDescriptor afd = null;
        try {
            afd = getAssets().openFd("Theme.mp3");
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength()); 
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            player.prepare();
        } catch (IOException e) {
            e.printStackTrace();
        }
        player.setLooping(true); //restart playback end reached
        //player.setVolume(1, 1); //Set left and right volumes. Range is from 0.0 to 1.0
        player.start(); //start play back

Looking at a previous discussion on StackOverflow, and the referenced Android commit where this was introduced, the code above might not completely initialize the MediaPlayer object.

The KitKat example code for media playback suggests that you should call:

mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

immediately after you construct the MediaPlayer, and before you call its setDataSource method.
