Installed the latest generic image on my NUC (its an 8th gen i3). I get no sound in Kodi. Initially when i was messing around with it my audio choices were:
Default,Default output device(pulseaudio)
Built-in audio Digital stereo, hdmi(pulseaudio) <-- or something like that, I can't remember exactly now because currently it doesn't even let me go into the audio choice, its greyed out. When i was able to select an option neither one gave me gui sounds. Seems after attempting to play a video which didn't play audio it doesn't let me select anything anymore.
No idea what else to provide info wise right now but here is my debug log after a fresh restart.
EDIT:
So i decided to try to run a ROM in ES. It played with audio. Went back into Kodi and now the audio setting is no longer greyed out AND audio is working both in GUI and also in a movie. Reboot the NUC and no audio again and setting is greyed out.
