No I’m almost sure it’s playing it as 5.1 and not Stereo because the dialogues, which I set to the center channel, are only coming out from the center speaker. I can’t hear any dialogues coming from L, R, Ls, Rs. So it must be playing it as 5.1 audio, right? Also the environment sounds which I set to Ls and Rs are only coming out from Ls and Rs speakers. I can’t hear them in L and R speakers. Everything seems right except the music that I set in L, R, C which I can also hear in Ls and Rs. It’s weird.
