My audio output is being picked up by my audio input, even when no device is plugged in (lemmy.world)

I work remote and I'm constantly on a Teams meeting while working. My colleagues have been complaining for a while that they can hear my youtube video, if I have it a bit loud. I always figured my microphone was picking it up and never paid much attention to it. Reducing the video volume or the microphone volume would fix it.

Today I accidentally unplugged my headset and they could still hear the video. Nothing is plugged into the computer, yet they can listen to my video. Something is causing a loopback or something, I can't figure out what.

My system:

EndeavourOS
Pipewire 1.2.7
The folders /etc/pipewire/pipewire.conf.d/ and ~/.config/pipewire/pipewire.conf.d/ are empty, so I assume no filters are being used

I attached the output of qpwgraph. I'm not really an audio expert but it looks normal?

Let me know how I can fix this! Thanks!

What headset do you have? Where do you connect it?

I use a Beyerdynamic Custom One Pro with a Vmoda Boom ProX microphone. It connects to my internal audio card via a normal 3.5mm jack. The problem happens even after I unplug them.

This might be a shot in the dark but maybe it is some sort of induction? The audio may still be generated and somehow it is creating a current in the mic electronics

I'm not a electrical engineer so this could be horribly wrong

Any idea on how I could possibly debug that?
