Public bug reported: 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!
