What I have found out is that after boot these bits were set (obviously), a= fter = the audio activity, they were cleared (not all, since if the given DAPM con= trol = 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 need= s it. In short: the overall power consumption was higher after boot, than what wa= s = after for example the playback was stopped... -- = P=E9ter
