Please supply the ALSA state files for each stage of the process (the
initial state then the state after each operation).  That should let me
reproduce exactly what you're doing.

You can check the power state of all the driver components by looking in
/sys/bus/platform/devices/soc-audio/dapm_widgets and building soc-dapm.c
with #define DEBUG at the top will make it very much more verbose about
the power decisions it's making.

They're alises for the same underlying control for power purposes,
although there's some gotchas there...
