I want to connect my Denon stereo directly with spotify app.

[GunterKu]

I can connect my (android)smartphone with the "screen mirroring" function to my stereo and listen to my library, but it doesnt work with spotify. Is there anyway that I can use the screen mirroring function(or any other) in the spotify app to achieve a direct wifi connection to my stereo?

I know that it works with the denon remote app, but that takes years and is not as simple as it needs to be.
