After I got to install, it does not work on my system. I began to debug, and got caught up in this libreleec bash prompt does not have any linux commands I am used to, simply apt-get and sudo commands are not there, so I am lost without a standard command set.
LE has no sudo, because you're already root user after SSH login. Also no apt-get, because LE only uses add-ons for packages.
Workaround
Take a spare microSD, and install RPiOS (which has sudo / apt-get) with Kodi: Click!
Install an ALSA EQ (Raspbian is outdated, but instructions hopefully also work on RPiOS): Click!
If everything works, you can autostart Kodi on RPiOS, and try a similar approach on your Intel system (Ubuntu & Kodi).
