Hello,
I have just fresh installed Ubuntu MATE 16.04 on an Intel NUC5PPYH which has the latest BIOS installed.
Everything works fine except I cannot get any sound through HDMI. Video through HDMI works fine.
Under “Sound Preferences” the only device shown for sound output is “Built-in Analog Stereo”. Installing pavucontrol and alsamixer similarly do not show a HDMI device for audio output.
I installed the latest ALSA driver as described below however, it made no difference.

I then installed Ubuntu 16.04 and sound through HDMI works perfectly.
I really don’t know what else to do! Perhaps I should install MATE desktop on Ubuntu but that’s probably not going to be as well integrated as Ubuntu MATE.
Any advice appreciated.
Greggy.
