My Question or Issue

I'm trying to get the volume value of the Spotify Music Stream.
I am able to get it throw STREAM_MUSIC when Spotify is playing music from the Android device or while the Android device is connected to a bluetooth speaker.

But when I'm streaming from the Android device to my Spotify App on the Smart TV/TV Streamer, Android is creating a new volume stream called: "Spotify" (as in the picture)
How can I get this value?

Please help me understand how can I get the volume of this stream..
Thanks!
