I have a Vizio 4k tv that is connected to beam with HDMI ARC with an Apple TV connected to the Vizio on another port via HDMI.
When I call Alexa to turn on TV, my tv switches to the ARC input and I see a generic white screensaver thing. I have to manually switch to say HDMI 5 for AppleTV so I can watch something. If I turn off the TV with it last being on HDMI 5 and turn it back on using Alexa it goes back to HDMI ARC. How do I keep it at the Apple TV HDMI?
