well then you have additional issues with the DMI quirk for the firmware
selection in sound/soc/sof/sof-pci-dev.c,

      {
		.ident = "Google Chromebooks",
		.callback = chromebook_use_community_key,
		.matches = {
			DMI_MATCH(DMI_PRODUCT_FAMILY, "Google"),
		}
	},

which means you need additional kernel parameters to provide the
location of the firmware....

There's been multiple rounds of discussions with Curtis, we introduced
DMI_OEM_STRING but it's still not good enough, and now the previous
conventions are not being followed on what is a relatively old platform
already...
