I have installed a custom kernel for an unrelated issue and applied all the released package updates and the powertop report has changed.

The kernel is from bug 844957 : http://people.canonical.com/~ogasawara/lp844957/

Now the powertop reports 0 mW for the sound codec, and the overall battery drain reported is lower too (although not by 3.3W lower).

OTOH meanwhile I have found bug 834725, so I am not sure how much powertop reports can be trusted.

Later I will reboot back to official kernel to check if it is kernel or package updates that have caused this change.
