For the record.
I tried to install some updated drivers and they give me a lot of troubles and the audio sounds AWFUL (like underwater)
So we need to uninstall all drivers then install the drivers from scratch:
First, uninstall the driver of the audio Device Manager > Sound, video and gaming controller -> uninstall Realtek audio driver (if you can, then mark the option to uninstalls the drivers)
Then (in the menu),Device Manager -> view -> show hidden devices.
Then Device Manager >Audio inputs and outputs> uninstall everything marked as (Realtek(r) audio). It uninstalls the drivers for the speakers.
And finally:
a) you could install the drivers for your notebook or, if it fails then:
b) you could install the default (Realtek) drivers then, over them, the drivers for your notebook
