What I have found out is that after boot these bits were set (obviously), after
the audio activity, they were cleared (not all, since if the given DAPM control
was not in the path, it was left enabled either way).
Now these bits are 0 after boot, and only enabled, when a certain path needs it.
In short: the overall power consumption was higher after boot, than what was
after for example the playback was stopped...
