My laptop Asus GL553ve and i purchased it on 2018. the laptop came with pre installed windows 10 and i didn't resintall windows till yesterday. i had all my updates and drivers upto date. i've been playing game like CSGO and Apex legends and music on 7.1 surround on my earphone which is at playback speaker configure. after i reinstall my windows 10 yesterday and when i play Apex legends, the game audio was set on headphone/stereo, so, i went back to control panel -> sound -> playback -> speaker configure to change it back to 7.1 surround and i found olny stereo is available, now i cannot use 7.1 surround sound any more. i tried almost everything updating windows and realteak drivers but still the same. please help, i'm worried that i've lost my sound.
