Before getting myself an external ssd, I was tight for storage space on my PC, so I use windows cleanup tool to delete some non essential files. An option was to delete files that had something to do with drivers. I figured that it could not be that bad since it was Windows suggesting it. So I did it. It work great for freeing up some space, but now every time I plugged in a new audio device (every switch from speakers to headphone jack) it would have an annoying popup something Realtek could not be started. Added to that, the first time plugging in headphones it would not recognize them, only the second time it would. Being annoyed after a week I thought I would fix it. I looked up a tutorial followed it, it did not work. I ended up deleting the "problematic" driver thinking I could reinstall them from the Acer driver downloads, but those don't seam to work for me. I tried the one found on Realtek's site, also no results I have been trying for the last week to get audio back to my laptop without other devices (bluetooth or hdmi). But nothing has worked for me.
