No audio in Dell XPS 9360 - Windows 10

Hi everyone,

the audio device of my Dell XPS 13 9360 stopped working in Windows 10, the volume control says "No output audio devices installed". Audio works fine on my Ubuntu partition, so it's not a hardware issue.

I tried to re-install, upgrade, downgrade the Realtek drivers, but no luck. Also tried to install the generic Microsoft High Definition Audio drivers. The system is fully upgraded (both Dell drivers, BIOS and Windows 10).
