One more datapoint: /sys/devices/platform/soc-audio/dapm_widget
contains the values below, and the difference compared to
gsmhandset.state is only these:

which seems a bit *too* small to me. In particular, I'd like "Right
Capture Volume" and/or "Left Capture Volume" to be set to on instead.
From looking at the diagram, I think that would make sense at least. I
haven't figured out how to affect these still from looking in the state
file and in the driver though.
