I've tried using a splitter cable for this to seperate the mic from the headphones but it doesn't really work properly. The best way I can explain this is when i'm on a discord call, and I'm listening to music or playing a game etc (anything with audio) the people im on the call with can also hear it. even if my headset volume is at 0, or if i use the mute button on the headset. This doesn't only happen on discord, it happens on EVERYTHING that requires me to talk to other people on PC.
