Let us test if disable power_save_node help or not.

edit /etc/modprobe.d/snd_hda_intel.conf to add:
options snd_hda_intel patch=onboard-patch

and specified the hint in /lib/firmware/onboard-patch:

$ cat /lib/firmware/onboard-patch
[codec]
0x10ec0256 0x10280704 0

[hint]
power_save_node = 0


Reboot the system, and check if the hint is set successfully. 
$ cat /sys/class/sound/hwC0D0/hints
power_save_node = 0

If there is still noise, please upload an alsa-info.txt as well.
