There's an Apple Music app for Windows currently in beta, but it runs on Windows 11 only. I don't have a Windows laptop that will run Windows 11, but @Blackwood: if you're a subscriber, maybe you could try it and see if you can stream AM directly to your AVR via HDMI? (I wouldn't necessarily be put off by the comments; I've installed it--and run it, in stereo--on a freestanding desktop machine, and it's given me no problems.)
