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
