I accidentally deleted the Intel smart sound technology audio controller in the device manager (under system devices). I initially had a problem with the audio output. It meant that an audio output device was not installed. I wanted to fix this problem and just uninstall this Intel sst not delete it completely.
At the moment I'm trying to download the Realtek audio driver from the Acer support website (my laptop is an Acer aspire A517-51) but somehow it doesn't load the page for me, just displays an error message that this page could not be loaded.
I just did stupid things, I know. How can I get this Intel sst audio driver back, can someone please help me?
Omit or uninstall the Conexant driver. Your device has Realtek HD audio, so all you need is the Realtek driver.
Also try this older driver: https://www.realtek.cz/download-driver-nr-456-for-realtek-ALC662-and-Windows10-64bit.html
It still works best on many devices.
