So my left headphone doesnt work since few days ago, i thought it was just the headphone's problem so bought a new one, and dang its still the same. Any sound doesnt come out from the left side of mine. Tried to do some tutor in youtube but almost everyone did the same tutor (the sound control panel and balance one). Is there any other app or tricks that i can do to fix this problem? or do i need to meet a tech support or expert for this kind of problem? Please help, any opinion is okay, Thank you.
