"The sof-firmware is missing/buggy since 20.10, so everybody with a 2020 DELL XPS/Precision laptop has not being able to get any input/output audio since months already".
Do you have bug link for those issues? I doubt it is not the sof-firmware's problem, maybe they are soundwire audio machines, need to upgrade the kernel.
BTW, the sof-firmware in the ubuntu linux-firmware is also from sof-bin v1.6.
