- because you showed us every single screenshots in your initial post that are irrelevant to the actual feature that needs to be turned on manually, which proved the point that it wasn't turned on manually and would therefore not play stereo audio sources in the rear speakers.
You seem to think 5.1 computer speakers are like car stereo in that you listen to music and the front speakers in the front doors would make sound and the rear speakers in the rear doors would make sound automatically. No, that's not it. You have to manually turn it on which by the screenshots you provided in your initial post didn't even know the existence of such function until I pointed it point.
- of course nuking the pc is an extreme solutions, that's why I am only suggesting this extreme solution after me providing you help for 4 pages, after multiple tech support from asus and spotify giving you the cold shoulder.
Netflix on internet browsers can't do 5.1. If netflix the windows app can't do 5.1 on your computer even after you set your computer to 5.1, then there is something seriously wrong with your system.
- did I say you f'd up? No, I said you listened to the wrong people.
Do you think I suggest to you nuke your computer because I know precisely how you screwed up your system and not tell you how to fix it the correct way? It is precisely the opposite, no help from tech support, there are a million combinations of things that could go wrong by randomly listening to internet help. You kept on arguing about point (1) showed us precisely that you don't understand the problem and therefore will never figure out how to fix this problem on your own.
