The problem is definitely there for the built-in drivers which I've tested 
quite a lot. It's the primary usecase for me, as I tend to build minimal 
device-specific and self-contained kernels in Gentoo.

For builds with modules things are not very consistent. Live Ubuntu with an 
older (and probably vendor-patched) kernel works just fine, but when I pull 
Ubuntu kernel sources and build it with the mostly same config (including 
modules) it boots with no sound in Gentoo. Mostly same -- because I need nvme 
drivers to be built-in as I don't use initrd.

Is it possible to do with the built-in drivers?
