@MattDevo thanks for that, but not sure why this would only start with #0217 as claimed?

And for the Kaby Lake issue, is there anything we/I can do to work around this in the image or is it a kernel issue (which I suspect it is) and hopefully this will be fixed in 5.0 or 5.1...?

 lack of HDMI output on the KBL Chromeboxes started with your 9.0 test builds way back (unsure which kernel version, or which build added the snd_soc_skl driver), not a new thing. I think the issue is that the codec driver (rt5663) which works in conjunction with the snd_soc_skl driver fails to load, so no outputs get enumerated. Blacklisting snd_soc_skl allows the snd_hda_intel driver to be used instead, which successfully enumerates the HDMI outputs. I've not had a chance to look into it much, and since the blacklisting works w/o issue, I didn't have much impetus to do so
