Thanks for looking into that Hui. I have checked that with the user who experience it - you are right, the mic was working fine *without* the need to install firmware-sof-signed.
Regarding firmware: what do you mean by "original sof-firmware" in this context? Do you need dmesg from vanilla focal or from focal with the sof firmware from impish shipping in linux-firmware?
