can remote control cable box AND sound bar AND TV

Can any xfinity remote control my cable box AND my sound bar AND my TV all at the same time. 

Now I have the cable box and sound bar controlled with an XR11 but at a minimum I want to be able to control the TV on/off [and if I can get the TV volume too that's a bonus( usually tv volume is muted and sound comes from the sound bar, but on some occasions TV sound is useful)]
