I have just installed ubuntu on my intel nuc. I am trying to fix the fact I have no sound over hdmi. I found the supposed fix in the following instructions:

**No audio through HDMI (many flavors of Ubuntu): This isn't specific to the NUC as it seems to be happening on lots of builds, but it's easy to get around: Make sure your system is up to date using the Update Manager Add the following groups to your account: audio, pulse, pulse-access, video, voice In a terminal window run the following:

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

Reboot the system**

The problem is when I get as far as running "apt update" terminal doesnt recongnise the command. Has anyone any idea where I am going wrong?

Per the error, apt just isn't a command. You need apt-get and you'll need to prepend that with sudo to run them as root. So the last two commands should read:

sudo apt-get update
sudo apt-get install oem-audio-hda-daily-dkms

After successfully updating and it still doesn't work, post your NUC model and flavor and version of linux you are trying to use in your OP. – Mr.Lee Mar 28 '14 at 14:30
Thank you so much! So simple. Sound is working now over hdmi. I'm just getting the hang of doing commands as I'm new to linux, so thank you for your patience!!!! – albany Mar 28 '14 at 14:43
