Please could you confirm for me the functionality of Airplay on HifiberryOS with multiple devices.
I currently have a pi4 and DAC HD and airplay works well from my iphone with spotify and others.
I want to get another pi4 and Dac setup in another room. If i do will i be able to play to both of these devices at the same time via my iphone, or will it just be one at a time? Plus can I adjust volume independently to each pi4?
