Have you also tried with the normal profile and and no kernel commandline
option?

IOW, please try with:
-The normal (not the Asus T100HA) chtrt5645.conf and HiFi.conf, so
  the input will be named "Internal Analog Microphone"; *AND*
-No kernel commandline option, check cat /proc/cmdline does not contain
  chtrt5645 in there

Since you were not using the UCM profile initially it might very well
be that your laptop has a normal analog mic and things where not
working before because the profile was not loaded.

Hans
