More generally, can Ubuntu be installed on an Intel NUC, and audio configured to work at all? I've seen lots of recommendations for the Intel NUC as a good Linux-box - I can't believe everyone else would have missed audio being broken.I have a problem with a specific usb audio device. Of course, it also says to "enable audio" in the BIOS - the only thing I found in the BIOS was "HD Audio", which was checked - maybe there's a setting missing.

One reason I'm looking for the drivers to install (or re-install), is based on Intel's docs at Troubleshooting Intel NUC, which, forįront panel 3.5mm audio jack isn't working. (It does say it's only for a much older kernel). Which are two years old, and I can't get to make correctly.

I think it's the lack of Realtek drivers, and this is the only thing I've seen in questions, that I haven't yet tried.

(The only output-source is "dummy", which is what I feel like). Everything is good, except I have been unable to get audio working. I have updated the BIOS to the latest, and enabled "HD Audio". I have installed Ubuntu 20.04 on an Intel NUC nuc10i7fnh box, with no problem. Is there an official source of Realtek Audio Drivers, that can be installed on 20.04 (a NUC, if that matters)? And what are the installation instructions?
