Comment in hda_intel.c states that 'the explicit resume is needed only when POWER_SAVE isn't set', but this is not true. There is no code that will automaticly power up the codec on resume, but only code that powers it up when user accesses it. So if user leaves a sound playing, codec will not be powered To fix that I check if there are any codecs that should be powered codec->power_count, and if so I power them up together with main controller.
