Random BABABOOEY sound effects, sometimes it gets a bit stuck like bababababa booey. Sometimes it goes slow and really slowly fades out like a bad echo. I don’t know what to do about it and it freaks me out makes me think I have a virus.

Windows 10. Programs running: FireFox, Telegram, and discord in the background (inactive) No tab on FF is indicating that it’s making a sound. I am killing most tabs now but it didn’t really change anything. Already ran a WindowsDefender virusscan. Can’t really see a suspicious thing running in the background: [https://i.imgur.com/LlDtbIh.png](https://i.imgur.com/LlDtbIh.png)

What do I do now?

Edit: It has stopped completely, I did not do anything to make it stop as far as I can tell.

People suggesting a prank by a coworker because I left my computer open: I’m unsure where you are from but in my world, there is a pandemic going on now.
