Hello Gentooers,
I could use some help getting sound to work on the above hardware.
Googling shows that there has been widespread difficulty with this
sound card on many distros. I haven't found a consensus on how to get
it to work. Some folks have resorted to blacklisting various sound
modules in modprobe.d. However, it does seem to work on Ubuntu,
specifically ubuntu-22.04 (which uses a 6.6 kernel) and ubuntu-25
(which uses a 6.14 kernel).
I did get sound to work on the 6.6 series of gentoo-sources by copying
things from ubuntu-22.04. Enabling SND_HDA_CODEC_HDMI was critical to
success as was using ubuntu's /etc/modprobe.d/alsa-base.conf.
When the 6.12 gentoo-sources arrived, I built a 6.12 kernel starting
with the working 6.6 gentoo-sources and doing a "make olddefconfig".
That's my usual kernel upgrade technique. But there's no sound. I have
read that sound has received a substantial reworking between the 6.6
and 6.12 kernel series.
On gentoo-sources-6.6.92, dmesg gives:

I don't really know how to interpret the dmesg outputs, but it seems
that the 6.6.92 output indicates that it has identified several card0
devices. The 6.12.31 output is missing comparable output. This
difference is reflected in /proc/asound/cards.
In 6.6.92, /proc/asound/cards contains
0 [sofsoundwire ]: sof-soundwire - sof-soundwire
Intel Soundwire SOF
But in 6.12.31, /proc/asound/cards contains
--- no soundcards ---
I'm completely lost. Does anyone understand how to get modern Intel
sound to work on modern kernels?
Thanks in advance for any ideas!
