To be more specific, I have sound on Lenovo 100s (orco) and Acer R11 
(Cyan) - with a known bug on clock configuration for the latter.

Asus T100 has multiple versions,the TA and TAF which use different 
routing. With the old driver we have a dynamic run-time set of quirks 
that select the relevant I2S, it's not there in SOF yet. It's on my 
to-do list but at the moment I would not recommend this platform.
