While not strictly required for MediaSession, RemoteControlClient used on API14-19 devices, does require audio focus and it is 100% strongly recommended for all media playback.

Adding lines such as:

AudioManager audioManager = (AudioManager)
    getSystemService(Context.AUDIO_SERVICE);
int result = audioManager.requestAudioFocus(this,
    AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);
if (result != AudioManager.AUDIOFOCUS_GAIN) {
    return; //Failed to gain audio focus
}

Before playing any media should gain audio focus and show controls.
