Just a weird one i noticed, when push to talk is used it sometimes activates my webcam it is a Microsoft Life Cam, It has an LED that turns on when it is in use. (i made sure current active mic wasn’t the webcam) It appears to mainly happen in mini putt. Just thought it was odd.
The drivers are probably programmed (or have a setting) to detect if an application uses a mic and/or webcam and turn on the camera when any microphone plugged into the system is activated.
I hope it’s not hardcoded, or else some software developer is terrible at his/her job
