loud buzzing sound when watching video

[Gazi]

Hi, every few weeks i have this weird, unexpected, loud electric/buzzing sound coming out of speakers. it happened a moment ago. i was watching low quality video on yt and in middle sound disappeared for few seconds, then there was 2 sec buzzing sound, i rewinded it and there was still no sound, i rewinded again and everything was fine. I think it only happens on YT, but once happened when was watching movie with my media player. Never happens when playing games.

i bought new pc recently and didnt have such an issue on my old one. my pc is:
i5 6600k 4.4 ghz 1.264
2x 8gb 2400mhz
asus z170 pro gaming
gtx 1060 6gb
windows 10 64 bit

If it only happens while on the web, what web browser are you using?

Sounds like a loose wire. Make sure that the inside of the case is clean and check all your wires and connections.
