Public bug reported:
What I have made to find workaround/fix:
1. The newest kernel 4.10.1 - does not help.
2. The newest alsa-utils and alsa-libs (1.1.3) - does not help.
3. Mute master - does not help.
4. Mute micro - does not help.
5. Disable Intel Power Save - does not help.
I still hear weird noise - like internal sound of graphics card (or
something else) - when headphones are connected. The noise occurs when
music plays too. I have one jack input for headphones/external
micro/headset. When I switch input from internal microphone to external
microphone or headset microphone, noise disappears.
My graphics card: Intel 620
Processor: Intel Core i5 Kaby Lake
On Windows 10 the problem does not exist.
