Unable to use StandardVisualizer with output mix (sessionId 0)

[bloodyraoul]

Hello,
When I try to use the library with sessionId 0, i receive empty audio data in onWaveFormDataCapture or onFftDataCapture. This occurs only on some devices, like a Nexus 6P.
I have the bug with the Visualizer class and I was hoping this library fix the issue because you tell it in the readme. Or maybe I didnt understood something or not use it the good way ?

My code to init the visualizer is :
IMediaPlayerFactory factory = new StandardMediaPlayerFactory(getContext().getApplicationContext());
IVisualier visualizer = factory.createVisualizer(0);

something wrong ?
thank you for your help
