They think thats is better to split this driver in two to avoid complexity, one to 8101 and 8125 and the other one to 8168 and 8169 (fiction or something like broadcom b43 legacy drivers)
In your situation I would compare options between .configs in both kernels taking "M" as a "Y" and look for one option disabled in the recent one. If you find one, check it if its needed for your hardware.

It doesn’t address snd_soc_sof, which appears to be necessary for this hardware.<https://wiki.gentoo.org/wiki/ALSA> and in particular boot with Ubuntu, or whichever liveUSB allows your audio to work and run: lsmodThere are 39 modules whose names begin with “snd_” or “sound”. The list is the same on the working ubuntu-25 and the non-working gentoo kernel 6.12 systems.lscpci | grep -i audio Same output on working ubuntu-25 and non-working gentoo kernel 6.12 systems. lspci -knnSame output for “Multimedia audio controller” entry on working ubuntu-25 and non-working gentoo kernel 6.12 systemsThe above will give you a hint as to what drivers are required. In addition, the output of dmesg will show any firmware your hardware needs.Both working ubuntu-25 and non-working gentoo kernel 6.12 systems load the same firmware and topology files.I expect you would need to emerge: media-sound/alsa-utils sys-firmware/sof-firmware Already emerged these. And they’re up to date. Finally, you can compare Ubuntu's output of 'zcat /proc/config.gz' with the audio modules you have enabled in your kernel and add what's relevant to your hardware.There are a *lot* of audio modules in use according to lsmod. But they’re the same in both working ubuntu and non-working gentoo. It’s difficult to compare the working ubuntu config (based on a 6.14 kernel) and the non-working gentoo config (based in a 6.12 kernel). But I’m thinking that the identical lsmod output implies that the gentoo config supports the necessary hardware.I appreciate your ideas!I’ve noticed that using ubuntu’s /etc/modprobe.d/alsa-base.conf was crucial to successful sound in gentoo with a 6.6 kernel. Given that I appear to be using the same kernel modules as ubuntu, and the same firmware and topology files, perhaps my problem lies in how modprobe.d operates? Unfortunately, I do not understand what ubuntu is doing with alsa-base.conf.John Blinka
