With a bit of tweaking, I figured that enabling power management on
on "Audio codec":
echo '1' > '/sys/module/snd_hda_intel/parameters/power_save';
helped a little bit. But not that much. Now on 4.14.33, I get 10h,
while on 4.16.1 I get 5h.
There is something else.
By the way, how do I make the above /sys/ tweak permanent on GuixSD?
