The sound works with Ubuntu 22.04. This laptop family (Dell XPS) is listed as
supported by Ubuntu on their site. It is the same hardware as the Dell XPS 13 Plus:

The Ubuntu/jammy 22.04 kernel includes this same list of modules as listed in
kernel.org issue:

$ grep -i CS35L41

This machine is setup with Secure Boot, and not setup to sign its own kernels.
So testing it in Debian would not be easy for me until its shipped in a signed
kernel.
