I have software (Reflector 2 and Airserver) that allow me to stream over AirPlay 1 from my iOS device.
However, AirPlay 1 does not allow me to use the multiple device feature built into AirPlay 2.
I can AirPlay 2 from my Mac to my HomePod and Apple TV and get all three devices playing the same stream. However, I can't control the music with my iOS device.
Is there a way I can play a stream to my Mac, AppleTV and Homepod from my phone?
