Hi I have just installed ubunutu on my intel nuc with a celeron n2820 processor. I am not getting any sound over hdmi. I have tried installing to pulse audio app with no luck.

  • Have you tried running alsamixer, to see if the HDMI audio device is active? I normally install and run pavucontrol to use Pulse Audio for configuration, not sure if that's what you did? – Ash Mar 28 '14 at 11:00
  • I have run alsammixer and here is the result imgbox.com/FOBwNxFg – albany Mar 28 '14 at 13:15
  • I am not sure whether this could be an issue with the bios? – albany Mar 28 '14 at 13:15
  • It's been a while since I've used Alsa, I think you need to press F6 and select the HDMI device and make sure it's enabled? – Ash Mar 28 '14 at 23:35

Ok so here is the fix I found for the nuc. Sound over HDMI works no problem after this:

sudo add-apt-repository ppa:ubuntu-audio-dev/alsa-daily
sudo apt-get update
sudo apt-get install oem-audio-hda-daily-dkms

Thank you for your help!
