Good to hear. So a part of the problem was the incomplete kconfig
setup. It worked casually because HDA-Intel was probed first in the
first, although basically SOF Alderlake driver should support it.
Since your config disabled SOF Alderlake, the HDA-Intel was probed as
a fallback. Now, by some subtle change, a different driver (AVS) gets
probed, and it failed.

I believe we should drop the Alderlake entries from AVS probe table
unless the firmware becomes available publicly. (FWIW, this case was
RPL_S).

Cezary, Amadeusz, what do you think?
