@Olivier, I installed a Win10 yesterday with no activation key, and ran the upgrader tool in a old HDMI TV, and the upgrader said it cannot upgrade (according the PDF is because my TV is not HDMI 2).
Anyway, I ran a workaround: edited pulseaudio config to power off the display for 1 second and my sound is now working (at least for the applications I'm running).
