Running the audio debug script outputs this (Failed to connect to bus: No medium found does not appear anymore, unlike earlier):

I installed pavucontrol to see the config profiles. Switching the speaker profile from off to “Pro Audio” gives 5 output devices all named Comet Lake PCH-LP cAVS Pro /2/3/4/5
Audio only works on Pro 5-only after setting it as the fallback device
This same issue happened this July and the fix I used then was to install alsa-ucm-conf, which is already preinstalled on LMDE.

You may need to add 'iomem=relaxed' to your kernel parameters,
or trying running from a Live USB with a more permissive kernel (eg, Ubuntu 23.04+).
If you have UEFI SecureBoot enabled, you need to disable it to run the script/update your firmware.
MrChromebox Firmware Utility setup was unsuccessful

I’m not quite sure how to disable Secure Boot.
