I have a Turtle Beach Earforce M3 gaming headset. These headsets have a single jack for both microphone and speaker, but a splitter was included in the box which I use on my PC. The headphones work perfectly fine, except for one issue. My computer audio is also transmitted through the mic, causing my friends to hear everything from my PC, even their own voices. This causes echos and alot of issues. Is there a solution for how i can fix this, any help would be appreciated.
