Linux can control volume on HDMI just fine. I guess it’s my expectation that on a desktop, I can control volume that the desktop emits, whereas with some appliance like an Apple TV or game consoles are solely built for streaming to a TV, and don’t have keyboard input etc, and for which it makes much more sense to just disable that control.
