I have the Logitech Z506 speakers and was wondering if I have it set up correctly for surround sound. I simply have a 3.5mm jack from the subwoofer receiver straight into the TV. Does this mean that anything that is played on the tv, IE Xbox One, Netflix app on the TV, Fire Stick etc will automatically play in surround sound? Can the TV know it's surround sound or would it just treat it as normal speakers? Or have I completely misunderstood what I am doing?
