The appletv is in the closet, but the other devices don’t make sense there. The linux box is about as big as a decent USB hub, and has a few wired game controllers plugged into it. The console is a switch, and going into the closet is too much trouble. I could put the sonos in the closet, but the play/mute button on it is too convenient when I don’t have a phone handy. The other stuff is self explanatory.
Can you not get a surround sound audio receiver/amp anymore? The digital out on the tv presumably would feed it. I had an old one like that, but it died.
