The sound was I think the same as when I complete a file transfer from one drive to another. I didn't unplug anything, didn't do anything weird, just browsing as usual, what could've caused the alert to sound?
Like I said in the original post, it sounded like a "file transfer" sound. I Youtube'd Windows 10 sounds and it was the "Background" audio. But I had nothing running.
I know it's hard to understand that I was just browsing chrome, not downloading, do nothing just reading and then I hear a random background sound even though like I said I was doing nothing. If anyone knows what could've caused this or how I can find out that'd be great.
