sound broken after win10 auto update, and driver reinstall didn't fix
Hi. I know this is an old thread. I am having a similar problem. Sound was working fine. An automatic win10 update caused the issue. "No audio output device is installed". Sure enough, playback devices is empty, nothing to select. In device manager, I have three drivers that are unsigned (code 52): a "Realtek High Definition Audio" under Sound, video and game controllers, and two "High Definition Audio Controller" under System devices. I have uninstalled/rebooted/reinstalled several times, no luck. The system ones don't really seem to uninstall - if you scan for hardware they come back. I'm not finding any other info anywhere else so hoping someone here can help me. My system is a Lenovo K450e with win10 installed on top of win8.1, and my audio is old school audio jack to headphones.
