Hi again,

We got a reply from https://bugzilla.kernel.org/show_bug.cgi?id=205293:

However unlikely that suggestion sounds, it's spot on:

    # modprobe snd-hda-codec-hdmi
    modprobe: ERROR: could not insert 'snd_hda_codec_hdmi': Key was rejected by service

Indeed, when I modprobe --force snd-hda-codec-hdmi and then rmmod/modprobe
snd-hda-intel, everything's fine again, including HDMI profiles.

So the new modprobe.d workaround is:

    install snd-hda-codec-hdmi /sbin/modprobe --ignore-install --force-modversion snd-hda-codec-hdmi

And there's something horribly wrong with the Debian build of modules, it
seems. I wonder what else is broken on this system because of a badly signed
module... :-/
