try to install firmware-sof-signed dpkg terminates with the error saying that
the sof files are already installed by linux-firmware, but the required file
In my readings without the snd_intel_dspcfg.dsp_driver=2 the system uses
sof mode which requires the package firmware-sof-signed. But I can not
do any testing about that from live system so I will do when I changed
permanent to 21.10 and provide the results.

Based off the bug comments its not clear to me if the debdiff for Focal
actually ended up resolving the issue for people. Additionally, the
debdiff is rather out of date as there have been a couple of SRUs of

I updated today to 20.10 and tested.
