As already said, Jason, my slackware install still have a working
audio after all updates.
I have installed slackware the common way, makeing it use BTRFS,
installed by booting
it , run setup on slackware64-15.0 installed all packages except KDE
as I use XCFE or GNOME.
Since gnome is not part of Slackware I am on XFCE right now. After I
installed slackware64-15.0
I boot into it, and then followed the steps in your AUDIO section from
step 1 to step 5.
So basically copied firmware into /lib/firmware, /lib/firmware/intel
and opt/google/dsm
After that I have reboot and sound was working already on kernel 5.15.80 .
Then I run slackpkg update and upgrade-all to update everything to
slackware64-current,
which at the time had a 6.1.8 kernel.
Slackware usually ships an unpatched kernel supplied as it is from Linus tree.

Thats it, and initially I know sound was hanging sometimes. But today
I do not experience any hangs
anymore.

Only thing I had to do was to enable the kbl-r5514-5663-max profile in
pavucontrol. As by default it was at
off position.

But if needed any file or log from Slackware instsall let me know.
