Topologies for most common skylake driver configurations: - skl/kbl with i2s rt286 - apl/glk with i2s rt298 - <any> with hda dsp can be found in alsa-topology-conf [2]. Standard, official tool called 'alsatplg' is capable of compiling these into binary form which, after being transferred to /lib/firmware/ may be consumed by the driver during runtime. I have no problem with providing precompiled binaries to linux-firmware, if that's what community wants.

I think the guild [1] is too complicated for normal users to fix the problem. Given it's not only the internal microphone being affected, it's no sound devices being created at all so no audio functions can work after kernel 5.8. Is there any potential problem to built-in the "<any> with hda dsp" precompiled binary in linux-firmware?
In general, linux-firmware is not the place to put driver-specific configuration files. It'd best to have standard UCM/topology files being build and honored during disto image creation.
In regard to the guide, thanks for checking it out. What do you think could be improved so that normal user has easier time with it? Feedback is much appreciated.
