my phone cannot play stereo over 3.5mm headphone jack

recently I tried to run android games on my laptop in *Gameloop* emulator (shooter games in general). after playing a couple of minutes in ***PUBG Mobile*** with the same headphone on, I noticed that the audio direction and footstep sound are far more clear and accurate than what it sounds on my mobile - I have a non-rooted Xiaomi Mi 9T Pro with the latest MIUI 12 on it. - and a headphone I purchased from a local store. I saw **this question** on this site, and if I'm not wrong, it says that I cannot play more than 2 channel audio on a 3.5mm headphone jack! But since I was able to hear more accurately on my pc with the same 3.5mm audio jack(aux), I am thinking that the android was the problem. Is there something I can change on my phone to make it output sounds like my pc, or even make it a little more accurate? **PS:** another thing I want to mention is, my mobile doesn't even split left or right channel while playing surround videos on youtube. I cannot tell if the sound is completely from the left channel or right because both sides of the headphone play the same sound. thanks for your suggestions.
