I have notice over the course of my time with xbox one...that whenever I play a movie, via xbox video or blu-ray; I have to keep messing with the sound options to be able to hear anything properly. (properly being sarcastic, sound becomes non-surround)
with 5.1 set, I get music, background noise, etc, but NOT speech directly in "front" of the "camera". It comes in very muffled on the other speakers and sounds really far away.
Current setup is the xbox to my home theater to my tv.
again this is NOT A TV BOX ISSUE...seeing as everything I search for surround wise ends up linking me to that problem...
