cd /sys/module/snd_hda_intel/parameters
then cat power_save then the value get 10 and in power_save_controller it is N

To make the change permanent, create a file at /etc/modprobe.d/sunrise-point.conf (as root!) with the following content:
options snd_hda_intel power_save=0 power_save_controller=yes
Then reboot.
See `man modprobe.d` for more on this method.
