My questions are as follows:
Question #1. Do I set Windows as 2 channel and upmix to 7.2 via Receiver (Dolby, DTS Neo... ect.) or do I set it to 7.1 Via windows Audio output and only have 7.1 from things mixed in 7.1 native? (eg. what are pros and cons of each)
P.S. What I mean to ask is should the mixing be handled by either the windows sound drivers or should the mixing be handled and/or upmixed by the AVR?
Question #2. How does my avr upmix a stereo signal and be able to separate the channels according? Vocals only coming through center channel blows my mind when I notice its upscaled from stereo for instance, Like how does my avr detect something as a vocal channel in stereo (is it frequency? phase?) im not sure but its kinda mind boggling.
My Avr is a Pioneer VSX1130-K for anyone wondering.
