--- Comment #22 from Takashi Iwai <tiwai at suse.de> ---
snd_hda_intel.power_save_controller=0 should work.  But better to check
/sys/module/snd_hda_intel/parameters/power_save_controller value.  Also, note
that some desktop environment may change this value dynamically depending on
the battery/power status.
