I've seen alot of people have this problem and i've searched for a fix on youtube, but all of the fixes didn't work for me, the problem was that the balance button didn't exist in the settings, this tutorial will replace the button.
I had the problem too so i searched for 12 hours to finally find a fix for this problem, the only reason why it took 12 hours is because there were alot of programs/softwares tested for this fix, this also works for wireless headphones aswell!
