I just installed Realtek audio driver from the official Acer site because I was having some sound issues; now everything is fixed but the issue is Dolby Audio isn't working. I mean to say that it is showing "Plug in headphones or speakers to enable Dolby Audio "! What should I do to solve this problem? Please help me if you know the solution. I really need this software since it enhances the gameplay. I have also attached a cropped screenshot for reference.
