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.
