I checked on these articles on powertop...i manually set it the value to 10 for *POWER_SAVE_DEFAULT but still don't see any power saving...
Check whether it's really set to 10 in /sys/modules/snd_hda_intel/parameters/power_save.
Also, the power-save is turned on only when all analog loopback switches are off, e.g. Mic Playback Switch or Beep Playback Switch must be off. Otherwise the analog part must be powered on.
