My Question or IssueI would like to listen music completely original stereo sound and I hate that 5.1 upmixing can't be turned off. There is many topics for that issue but nothing happens to solve this stupid feature. If i put settings on xbox menu to 2 channel stereo the sound is totally **bleep** vs. 2 channel stereo from analog source with spotify. My 5.1 setup is good quality with hi-end front speakers and REALLY WANT TO GET PURE STEREO SOUND that respects original recording!!!
