Support seems to be there in chromiumos:

There is also ACPI that registers the audio codec apparently (grep to TI_SWITCH):

https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/release-R52-8350.B/src/mainboard/google/cyan/acpi/mainboard.asl

Could it be an issue with ACPI? ChromiumOS triggering different functions in ACPI compared to mainline Linux, and initializing via ACPI the codec?
