While IR communication still has a place, the low signal, unidirectional, line of site required technology does not find its way into many modern day devices. Except entertainment media component remote controls, of course.
Because of this, unless your media components support WiFi, Bluetooth or NFC you are going to need to keep track of that remote. That is unless you get your hands on the HiRemote from Chineese startup commpany called Jeeqi. This device plugs into the 3.5mm jack on your smartphone and has an associated app that lets you use your handset as a IR blaster to control your TV, Blu-ray and other components. No more looking through the cushions for the remote.
