Xbox One Adjusting volume on Xbox One

[Dobby]

I'm currently controlling my Xbox one with the phone app, however I can't turn the volume up/down or power on/off my TV.

I'm not sure why I can't, the newer slimmer xbox has something called an "I.R blaster" built inside. I'm not sure if my original xbox one does.

I don't have a connect nor do I want one.
Does anyone know to do??
