Need Help With Headset Sound

Hello, I've been having problems with my gaming PC and the headset I'm using with it. The current headset is a Logitech G231, but I've had the same problems with a few past headsets. Basically any sound from my PC that plays through the headphones can be heard by everyone in voice chat with me, including game sounds, YouTube, and Spotify. I've tried a lot of things such as the microphone levels and input and output devices. Does anyone have any advice on how to fix this problem?

If you've had the same problem on the same PC but with other headsets then it's probably a PC issue. Since the Logitech has it's own mic have you tried disabling any other mics (such as on a webcam?).

Are you sure your audio drivers are up to date?
