Wildwood sound playing even tho master volume is set to 0

Hope the imbed works correctly, but ive added a 2 screenshots and video, if u listen around the 4 second mark this weird ambient sound plays even tho my master volume is set to 0. it happens every few wildwoods and seems random.


just incase https://imgur.com/a/KnEieh2 here is the link to the imgur

edit: imbed vid does not want to work

imgur embedding requires the actual image url not the webpage url
it would be https://i.imgur.com/YO8dNJf.mp4 not https://imgur.com/a/KnEieh2 but I doubt mp4 embedding works

fixed it partly, but vids do not work yes
