System audio leaking to mic

[KeisukeTakatou]

I have a Logitech G pro headset and when I was talking to my friends on discord they were telling me that they could hear stuff like youtube videos, games etc. and so I tested this out by going to audio settings and selecting "listen to this device" for the mic to be listened on my monitor speakers. I turned the volume down completely from the headsets analog volume adjustment wheel and then opened a youtube video and I actually could hear the video although very silent from the monitor. There was no sound coming out of the headset for the mic to pic up  so somehow the audio going to the headset is also going to the mic. Funny thing is that when I connect the headset to behind the pc directly to the motherboard (it was normally connected to the front panel on the case) the problem dissapered but now there was much more static in the microphone. Stereo mix isn't even in the recording section or anywhere else so I don't think that's it.

Sounds like you have some god awful onboard audio. This is a situation where either a dedicated sound card or another form of audio filtering would be really useful.

I have an asus tuf z370-plus gaming ii motherboard

I'm actually considering getting a sound card but I wouln't expect such thing from a mb like this.

I was thinking it was maybe the drivers because I get errors when installing realtek drivers.

Alright as stupid as it sounds after disabling my malware protection and reinstalling drivers it actually is gone. God I feel stupid.
