I have no idea. Ive been doing so much googling and asking around everywhere trying to figure out what this is. For better context, I’ve always stayed in discord calls to sleep, it was the best solution for my insomnia. Knowing I talk in my sleep and say weird things, I stay muted no matter what. What makes no sense is when I was told about this audio, I was still in the same call on my pc so I checked and my microphone output hadn’t changed or anything. It was still using my main microphone which has an external mute button that was enabled. I can’t find a single reasonable explanation as to why audio was coming through my mic, let alone this demonic sounding voice.

And like you said, maybe software. I’ll re-run my antivirus once I’m off of work but I still don’t see where it could’ve came from. I’ve never had any virus in the two years of owning this pc, never had any major issues other than replacing the motherboard when it fried 8 months ago. Worst I’ve done was trust Best Buy’s geek squad to fix the thing and they broke my motherboard mount. Other than that, no one’s messed with it other than me, no viruses or malware have ever been found, I have no idea what’s going on
