Thanks for sharing and good to hear that you have audio working. I have
no idea why BIOS folks keep inventing new (and illegal) ACPI _HID values...
We may need to use the same tricks as in sst-acpi to find out which
string to use for .codec_name based on which _HID is handled by the ACPI
subsystem instead of a hard-coded value.
Note that we are trying to move away from this older driver to a newer
one based on DPCM that would also support BYT-CR devices and MinnowMax
Board. It's not ready yet for upstream but if you want to add those
changes to the newer version and test it'd be great. See
https://github.com/plbossart/sound.git t100-v4.3-24bit and matching UCM
files at https://github.com/plbossart/UCM
