No sound on HDMI with Intel NUC

[Fulvio]

Hello,

I have just installed Linux Lite on my new Intel NUC DE3815TYKHE, and I have no sound on HDMI. My system sound report says:

===========================================================
Sound Information
===========================================================

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]

  Subdevice #0: subdevice #0

I found over Internet that, for another type of computer and another Linux distribution, someone says to change in etc/default/grub the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" and then reboot, but I think that I should put something different than radeon.

Thanks a lot
