airplay from iphone to apple tv (with volume control)
On a regular basis, I will download albums from Apple Music and use my iphone to play airplay music to Apple TV (and my home stereo), controlling volume with my iphone and apple watch.
Problem I'm having is that sometimes, the music will start playing INDEPENDENTLY from the music app on Apple TV and not from my phone and so I lose volume control on my phone. I DO NOT want it to do this, but how do I distinguish?
On a side note, the CORRECT function I want has an Airplay icon (concentric circles above a triangle) while the INCORRECT function shows a mirroring icon (square above a small triangle) though it is not mirroring my screen.
Thoughts?
