The init sequence needs to be applied in two different places: once in the init callback, and another in the resume callback but only for the hibernation restore. The patches below are applied on top of yours, and this should make things working. The first one lets the HD-audio core recording the currently processed PM event, and the second one evaluates it and applies the missing init sequence also for the hibernation resume. This isn't quite sexy, but it has the minimal change in the codec driver side. If this requirement is more common, we can think of splitting / reorganizing the codec callbacks to be more directly called from the device pm ops. thanks, Takashi
