Hi, I am experiencing a similiar issue. For me, it looks like the new kernel version 6.7.0 might have introduced this issue.
My system is a Dell XPS 15 9560.
After upgrading to the newest kernel 6.7.0, my audio devices were not available anymore and it just listed a “Dummy output”. Going back one Revision (6.6.8) fixed the issue. Currently I am using 6.6.11, which also runs fine.
These are the interesting parts in my kernel log:

There are people on Arch having similar problems after using 6.7.0 Audio partially broken after update (kernel 6.7) / Kernel & Hardware / Arch Linux Forums
