I have tried to install driver given from Acer official support and Realtek, but neither works. I also have tried uninstall completely the drivers and now they are all gone! I also tried to reset the computer but also didn't work out. Any solution will be appreciate!

    XiaoBAI firstly download the acer stock audio drivers for you model form the support page and try to install them if it wont work backup whatever you need create a recovery usb drive via acer care center if your recovery partition its still intact and not corrupted ( a good 16gb usb drive will do) then perform a stock recovery clean install check here select delete everything option if after this the issue its not solved its most probably hardware contact acer support and send it back if its still under warranty if out of warranty take it to a repair shop and if the sound adapter its faulty only a full mobo replacement will do at this point
