[SOLVED] SOF Driver can't load intel/sof/sof-cnl.ri

Because I have a relatively new laptop, my mic is only supported by the sof driver. I have installed sof-firmware, but it still won't work. I am not sure if my kernel config is wrong, or there is a problem with sof-firmware.
dmesg | grep audio:

I copied it over as described in that other thread, and I am no longer getting that error. But, I am still not getting any sound. Here is the output of dmesg | grep audio now:

1. I downloaded the package from here
2. mkdir sof (in ~/Downloads)
3. cp sof-firmware-1.5.1-1-any.pkg.tar.zst sof/
4. cd sof
5. tar -I zstd -xvf sof-firmware-1.5.1-1-any.pkg.tar.zst
6. cd usr/lib/firmware/intel/sof/v1.5.1
7. doas mkdir /lib/firmware/intel/sof
8. doas cp sof-cnl.ri /lib/firmware/intel/sof
9. loginctl reboot

OK... Try to add also usr/lib/firmware/intel/sof-tplg/sof-hda-generic-2ch.tplg (it's the path in the archive from Bugzilla; may be slightly different in your archive) to your system, to /lib/firmware/intel/sof-tplg .

I copied it, but it didn't make any difference. I also was trying to change my kernel config to fix these, I am not sure what I did. Now, something else appears when I do dmesg | grep audio:

Looks like firmware has worked... I see similar dmesg messages in that sof bug, they were related to wrong kernel configuration (CONFIG_SND_SOC*).

On Arch, I had a much newer kernel, like 5.7 something, so I tried that. It complained about another missing lib, which I copied over the same way as the first one. I have noticed something. On Arch, snd_hda_codec_realtek gets loaded where snd_hda_codec_generic gets loaded on Gentoo. I have snd_hda_codec_realtek enabled in my config. Also, starting with the line about topology, Gentoo dmesg doesn't show anything.
Here is the output of dmesg | grep audio on Arch:

Unfortunately I will have to reinstall Arch, I actually needed to anyway. I need Arch for school since I haven't fixed Gentoo yet.

There are good news:

bug

shared

Issues like these would rise less often if the relevant changes get merged as default choices in gentoo-sources?.. Not sure if it's possible though. Just a thought.

I have reinstalled arch, all I had to do was install sof-firmware and everything worked. Hopefully with this, I can fix the audio on gentoo so I can use that as my daily driver. Also saw that sof-firmware got updated to 1.15.1, and I didn't need to copy any libs from the arch package. That's awesome.

After I disabled CONFIG_SND_SOC_INTEL_SKYLAKE_HDAUDIO_CODE in the kernel, which they said is deprecated, I am getting new errors in dmesg.

After tweaking some parts of his config, I got everything to work! I'm so happy, thank you for helping me.
