I'd like to stream audio from my mac to multiple home pods and applet TV's around the house. I know I can do this via iTunes, but I'd like to do this with a local iHeart radio stream that I can only get through a website. I seem to be able to select one home pod via the volume options, but can't seem to select more than one. I have even tried creating a custom midi driver, but can only select one airplay2 device. Am I missing something? Are there any work arounds so I can stream local radio via the web throughout the house?
