[NEDM64]

Set up Kodi on a Ubuntu Server 16.04, no PulseAudio installed, it worked untill a reboot.

Kodi boots with via Lightdm autologin and runs as root (yes, I know).

Audio out is set up to HDA Intel PCH, MEI Panasonic-TV on HDMI.

It runs on a Intel NUC clone (Gigabyte Brix)

No sound played for media or interface.

aplay -l | pastebinit - your kodi reveals that there is _no_ hdmi audio device, which is an OS issue.
