This is because of a change in 2.6.34-rc1 ea52bf260ecbb175339af3178c15788df21b7516 ALSA: hda: Add powerdown for Analog Devices HDA codecs The problem was the added resume callback that doesn't consider the modified init hook. The fix is simply remove the resume callback here and make the resume normally. This doesn't change any behavior intended in the commit above (for shutting down the sound at suspend) but only fixes the resume.
