Alternating TV and surround sound

[XRA]

Equipment: Vizio V705-G3
Denon AVR-X1300W
DirecTV Genie H34
Chromecast Ultra

I originally had my Vizio connected via ARC to the Denon, as well as the Genie and CC Ultra. My question is how can my wife go about watching regular satellite TV without the receiver automatically coming on every time, just use the TV speakers unless it's movies with the CC Ultra. It's a big mess every time she just wants to watch TV and it ain't pretty, especially if I'm not around to deal with it. I've tried the PassThough stuff (I think), and can't get just the sat box and TV only to turn on. Think it would be easier to just not use the ARC at all, which I've done as far as the sat box, but now am trying to get the CC Ultra going with video AND sound. Have the video part down, but no sound thru the Denon.

Now I have the sat box going to the TV with an HDMI and optical cable, and it works fine, no Denon. I can switch to the Denon and get satellite through the surround sound. I am also trying the CC Ultra to the Denon, but am confusing myself all to heck. Can I connect the CC to the TV, then run another optical from the TV to the other optical on the Denon and get CC Ultra sound and video through the Denon? Can I also just watch the CC Ultra with TV speakers only?

I know I'm somehow making this harder than it has to be, but just can't figure it out.

Thank you.
