I have an Acer Aspire V Nitro (Aspire VN7-593G). I installed the new windows update today and Dolby Audio is nowhere to be found. Whenever I'm watching something on Youtube or on Twitch while I play a game, the audio would become really low. This was due to Dolby Audio disabling itself. I have no idea why this happens and I couldn't find anything substantial searching the internet. This wasn't a big issue as I would mostly use headphones. When I wasn't using headphones, I would alt tab and turn on Dolby Audio manually. I tried installing the audio driver from the acer website, but it didn't help.
