I'm using Fedora 25 since something like a year on PC with Z-170 Deluxe mainboard and I have some issues with USB/audio drivers. Every time a USB device (mp3 player, hard disk etc.) is being connected/disconnected audio pops. I've tested also headphones on front audio output port and it didn't change anything. Here is a video presenting the problem: https://videobin.org/+h8u/l9e.html
Previously I was using Thinkpad T61 and Arch linux and I never had such issues so I event don't know what to investigate in order to find the source of the problem. Please help.
