Reinstalled LibrELEC attached to TV HDMI port. Didn’t make a difference… no sound. So I installed latest Linux Mint Mate… still no sound or even mention of HDMI in the sound settings. But testing will be so much easier at the OS level vs stuck in Kodi. Yes I could turn on SSH to get to a command line in LibrELEC which is better than a sharp stick in the eye. But from Mint I can also work from the command line and I have access to a browser that I can cut and paste commands from and take screen shots, and audio/video players.
I can also have a few video and/or audio files available to quickly test things.
I chose Mate because I read it was fairly light weight. Installing it was fairly straight forward. After the Install there was still over 200GB available. The computer is very responsive, it has 6 cores.
I don’t know why audio over the HDMI is even a issue in 2026. I would assume a large number of Mini PCs would be attached to a HDMI TV.
I also assume there are way more articles addressing HDMI sound problems on any major Linux distro vs Kodi.
I also checked the DP to HDMI cable I bought, and it does support audio.
HDMI sound problems were the farthest thing from my mind. If I had any thoughts on this I would have tried to play a video under Windows before I wiped it off.
If/when I get HDMI audio working then getting it to work in Kodi should be a cinch.
It’s late so I’m going to wait till tomorrow, but I read something about disabling the Mini’s internal speaker in the BIOS (F10). I’ll try that tomorrow.
