BluetoothA2dp get Audio session ID

Question

I'm using AudioManager for playing songs. I want to combine it with Equalizer.

AudioManager manager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

int audioSessionId = manager.generateAudioSessionId();

EqualizerModel.getInstance().setEqualizer(new Equalizer(0, audioSessionId)); 

My problem is that I don't want to generate a new audio session ID, I want to get the current Audio session ID. How can I achieve it?

I saw a few examples with MediaPlayer, but I work with BluetoothA2dp.
