I have a Xbox One and a tv decoder (for cable television) connected via HDMI to the television.
Yesterday I've received and "old" Philips 5.1 Home Theater that doesn't have HDMI inputs, but only one RCA inputs.
My first question is simple: If I connect the TV to the Home Theater AVR, the audio output will always be a 5.1 ? If I turn on the Xbox One does the audio come out as a true 5.1 or does it simply sound like a stereo "adapted" to a 5.1?
If a simple connection like this is not effective (basically every device connected to the TV and the TV connected to the AVR) How can I set everything so that every device's output audio is a 5.1 ?
