me: working
my pc: suddenly starts playing some kind of videogame ad audio in my headphones
me: WHAT
Checked every open firefox tab, they all were silent. Opened Helvum, it showed that the audio was played by "Chromium" proccess. I didn't have Chromium open.
A minute later, I've realized. It was Steam. Playing the trailer of Apex Legends, without any Steam window open. I didn't interact with Steam in any way that could lead to this o.o
Steam regularly does some weird stuff. Like, randomly opens itself. Or randomly opens a chat with someone even when there were no new messages.
One time, I fell asleep with my PC unlocked. Steam opened a chat with someone jokingly asking me to fuck them. Someone else likely saw this.
