[N501VW, Realtek ALC668, Black Headphone Out, Right] Background noise or low volume

[Andrey Solodovnikov]

There is a background hissing/squeaking noise in my headphones every time I resume suspend.
Speakers and HDMI audio are not affected.
I've tried many solutions to fix it (alsa force-reload etc.), but none of them worked well.
More detailes you can find here:
http://askubuntu.com/questions/884051/constant-hissing-sound-after-suspend-asus-zenbook-ux501-vw

Standard four questions:
1) Ubuntu 16.04.1 LTS
2) Kernel 4.8.17-040817-generic (also tried 4.4.0 and 4.3.5)
3) When I resume suspend I hear no noise unless I play something
4) Right after suspend resume there is a background noise

Thanks!
