So this time, I'm really just looking for some insight. I apologise if this is the wrong board for this.
I went ahead and changed my setup so that my A/V receiver's HDMI out connects to my Xbox One's HDMI in, the latter normally being intended for cable set-top boxes and the like. My TV is now connected to said Xbox One's HDMI out. Now, I'm pretty much accessing my HTPC, and every other device connected to my A/V receiver, via my Xbox One's TV app. All of this is purely for the sake of experimentation, mind you; I can change it back rather easily.
I just wanted to know if there's any particular reason I
shouldn't do this. Centralising my entire home theatre system to my Xbox One is not an undesirable concept, considering that such is one of the device's primary stated purposes.
For the record, I tested audio playback with this setup. Working well so far.
On a related note, is it possible to control MC in theatre view with an Xbox One controller, likely connected to the HTPC via USB? It would be kinda cool to scroll through my media library with the D-pad.
