This is the actual audio I’m hearing scrolling through the memes thread 
what browser do you use? how did you replicate this? i cant seem to figure it out
for me it happens on firefox
I’m on chrome, pretty much all I have to do is start playing a video, pause it, and start scrolling away for a while
its a weird discourse bug then that theyve been struggling to reliably patch for years
just gonna have to live with it
