There are various places to modify this parameter (including the kernel
config, I think). So, you may want to check

$ cat /sys/module/snd_hda_intel/parameters/power_save

in order to make absolutely sure that this parameter hasn't been
tampered with. If you change this parameter on the fly, it will only
take effect after you have accessed the card through alsa, e.g. by
calling

# alsactl restore
