The last time a technician was here he programmed my 5.1 sound system to come on with the tv and X1 box. But the catch is if u change inputs thru the day it'll remember the last change and won't work correctly. We solved it by using a Harmony Remote. It was the Harmony One, not sold anymore, but still works exactly how I want after programming on my pc. Somewhere in the settings u can program your remote. Xfinity button, go right to the gear and it's down in there.
